Before the Khmer Rouge took over in 1975, Cambodia boasted a surprisingly vibrant rock scene loaded with Afrobeat grooves, psychedelica and trans-Pacific surf-rock influences. That spirit is carried on by Dengue Fever. The Los Angeles-based sextet is led by two brothers, Ethan and Zac Holtzman, who got turned on to the country’s lost sounds while traveling Southeast Asia. They found a Cambodian singer, Chhom Nimol, whose electrifying voice helped them become a breakout act at South by Southwest in the mid-’00s and earn a recording deal with Peter Gabriel’s Real World label. Another cool choice for the Ordway’s Target-sponsored world music series. (7:30 p.m. Sat., Ordway Music Theater, $23-$27.) Members of the band will be in town a night earlier to attend a free screening of the documentary “Don’t Think I’ve Forgotten: Cambodia’s Lost Rock and Roll.” (6 p.m. Fri., Capri Theater, 2027 W. Broadway, Mpls.) Chris Riemenschneider



After featuring mostly country stars and classic rockers from another era, Treasure Island Casino has booked pop-soul hitmaker Jason Derulo. He was all over the radio in 2014 with the playfully suggestive “Wiggle” and “Talk Dirty.” Last year, after seeing his high-profile romance with Jordin Sparks end, he landed on “So You Think You Can Dance” as a judge. He did manage one big hit from his fourth album — “Want to Want Me,” a slice of lite funk with verses that evoke Michael Jackson and an irresistible pop chorus worthy of Maroon 5. (8 p.m. Fri., Treasure Island Casino, $64-$79.) Jon Bream


– A Tribute to the Man in Black.” No one in town does Johnny Cash better than Sherwin Linton, his friend and Minnesota’s country king since the 1960s. Also appearing will be members of local groups Trailer Trash, White Iron Band, Eleganza and the Church of Cash. (9 p.m. Fri., Cabooze, $10-$15.) Bream


New band alert: Former Roma di Luna backup vocalist Jessie Daley and ex-Roster McCabe guitarist/keyboardist Drew Preiner have been basement-taping together for two years now and are ready to debut their electronic duo Fraea (“fray-ah”). Like former bandmate Channy Leaneagh of Poliça, Daley has a far-reaching, softly dramatic voice well-suited to atmospheric electronic layering. But in this case the songs boast relatively overt hooks and classic, sexy synth-pop flair, with traces of Goldfrapp and Everything But the Girl. They’re getting their sea legs as a live act ahead of a Poliça opening gig in March and their debut EP’s release in April. Dem Yuut opens, an electro-weird quartet featuring local sidemen such as Jeremy Hanson and Jef Sundquist. (11 p.m. Sat., Icehouse, $6-8.) Chris Riemenschneider


If you were to carve a Mount Rushmore of Twin Cities acoustic guitarists, Leo Kottke would certainly be among the quartet and the others might be a threesome sharing a stage for the first time this weekend — Tim Sparks, Phil Heywood and Dean Magraw. In the 1980s, Heywood won a national fingerpicking championship and an American Fingerstyle Guitar Festival competition. Sparks, maybe best known for his work with the recently reunited Rio Nido, won the 1993 national fingerstyle guitar championship and has since distinguished himself as a globe-trotting master of various styles of ethnic music from Bulgarian to Jewish. Similarly, Magraw, who also plays electric guitar, has covered a wide musical spectrum from Celtic and world music to jazz and folk, and performed on “A Prairie Home Companion.” The show is aptly billed as “Guitar Masters.” (8 p.m. Sat., Hopkins Center for the Arts, sold out.)

Best known perhaps for the 1960s/’70s Chicago blues ensemble the Siegel-Schwall Band, harmonica ace Corky Siegel has been exploring what he calls chamber blues since 1988. Call it a marriage of classical music and blues. When the singer/pianist/harp man/composer hits the road with Corky Siegel’s Chamber Blues Show, he pursues new possibilities, which will be the case when he’s joined here by saxophonist Ernie Watts, who has played with the Rolling Stones, Frank Zappa and such jazz stars as Charlie Haden and Kurt Elling as well as his own Ernie Watts Quartet. (7 p.m. Sun., Dakota, $30.) Bream


Back in the early ’80s, Metallica and Slayer opened for Venom, not the other way around. The Satanical British speed-metal band never had its big breakthrough moment — conservative backlash to its 1984 album “At War With Satan” is probably its main claim to fame — but it remains a favorite of old-school thrashers. The band has splintered into two different factions, one with bassist/vocalist Conrad "Cronos" Lant (not playing here) and the newer version that's coming our way, officially dubbed Venom Inc., which features heyday-era guitarist Jeffrey "Mantas" Dunn and drummer Anthony "Abaddon" Bray and latter-day bassist/vocalist Tony "Demolition Man" Dolan. They are on tour with a new album, “Iron and Steel.” Ohio horror-metal quintet Necrophagia opens. (8:30 p.m. Tue., Turf Club, $20-$25.) Riemenschneider


Already earning 89.3 the Current rotation with their sexy-cool single “Heartbroken in Love” and picked for First Ave’s Best New Bands showcase Jan. 15, Bones & Beeker are solidifying their live show with a monthlong Minneseries residency. The project started as a collaboration between longtime Brother Ali and Rhymesayers DJ Brendan “BK-One” Kelly and falsetto-loving Villa singer Anthony Newes, whose debut album offers a breezy and infectious mix of ’70s-flavored astro-pop and jazzy Latin/Caribbean grooves. They’ve expanded into a four-piece on stage with Poliça bassist Chris Bierden and former Atmosphere guitarist Nate Collis. The series continues next week with Lucy Michelle’s Little Fevers and Pornonono as guests. (10 p.m. Thu., Nomad Pub, free.) Riemenschneider


G-Eazy performances go a lot like this: The hunky, clean-cut, 26-year-old Bay Area hip-hop star cockishly slow-raps a verse, then he stands there and holds his microphone up to the audience for about 30 seconds while some prerecorded vocalist such as Chris Brown or Bebe Rexha sings a poppy hook. Repeat 200 times. To his credit, though, the real-life Gerald Gillum has a strong Twin Cities fan base that sings along loudly to both him and his canned accompaniment. After a 2014 Soundset appearance and two sold-out First Ave gigs last year, he graduates to an arena theater configuration in support of his second album, “When It’s Dark Out,” which debuted at No. 1 on Billboard’s hip-hop/R&B chart last month. A$AP Ferg, Marc E. Bassy and Nef the Pharaoh also perform. (7:30 p.m. Wed., Target Center, $30-$37.) Riemenschneider



“Timeline,” by the Chris Lomheim Trio, was one of the best jazz records of 2014, local or national, a string of contemplative gems from the pianist/composer. Lomheim performs a solo dinner set on a semiregular basis at the recently opened Vieux Carré in the old Artists’ Quarter space, but he’s best with his trio, especially if his longtime cohorts from “Timeline,” bassist Gordy Johnson and drummer Jay Epstein, are on board. Smart, acute music in a snug venue at a bargain price. (8 p.m. Tue., Vieux Carré, $5.) Britt Robson



Hats off to Ken Valdez, the Santa Fe transplant and current St. Paulite who has been working the trenches of local and regional blues clubs for years now. There is a rasp in Valdez’s vocals that’s tailor-made for the tales and tribulations he spools forth in classic Chicago blues-rock fashion, abetted by thunderous drums and his chunky guitar riffs. He’ll celebrate a new CD with guests Blue Rooster. (8 p.m. Sat., Famous Dave’s, $7.) Robson



The recorder is a survivor. By rights it should have fizzled out in the 19th century, as louder woodwind instruments evolved to serve the expanding symphony orchestra. The recorder stuck around, though, enjoying a new lease on life as interest in baroque music skyrocketed in the past half-century. St. Paul-based Cléa Galhano is a world-class exponent of the instrument, and launches “Latin Reverie,” her latest CD, with a recital featuring music by Villa-Lobos, Piazzolla, Pujol, Bach and others. Rene Izquierdo, another top-notch soloist, provides the guitar accompaniments. (7 p.m. Fri., Sundin Music Hall, Hamline University, St. Paul. $5-$20. Terry Blain


The grandest, and the cheekiest: Beethoven’s Third and Eighth Symphonies make a provocative pairing in the latest concerts of the Minnesota Orchestra’s Beethoven Marathon series, featuring all the symphonies and piano concertos. Music director Osmo Vänskä has a special grip on these perennial masterpieces, and is joined by outstanding Russian pianist Yevgeny Sudbin in the brooding Third Concerto. Framing Saturday’s concert are a fascinating preconcert opportunity to compare the sound of a modern concert Steinway with a fortepiano of Beethoven’s own period, and a late-night performance of Beethoven’s Septet. (8 p.m. Sat., 2 p.m. Sun., Orchestra Hall. $25-$96. 612-371-5656 or Blain
