POP/ROCK There are plenty of surf-rock revivalists floating around these days, but few featuring a grimy sheen like Portland, Ore.'s Guantanamo Baywatch. The campy, reverb-washed trio trades in by-the-numbers surf a la Dick Dale, a formula they deliciously muck up with Black Lips-ish slop and sneer. A choice collection of locals open, including Teenage Moods, Ice Rod and the Sex Rays. (10 p.m. Fri., Turf Club, $7.) Jay Boller
Nearly three years after their debut EP, Los Angeles-based pop-rockers Saint Motel -- featuring Minneapolis-reared frontman AJ Jackson -- finally have a full-length to tout on tour. A luscious guitar sound anchors the week-old "Voyeur" as it moves through effervescent toe-tappers with ornate instrumentation. A chipper swing runs throughout, bolstered by Jackson's bubbly croon. (9 p.m. Fri., 7th Street Entry, 18-plus, $8-$10.) Michael Rietmulder
It's not the big First Avenue festival originally slated this weekend (and put off until next year), but the club did book one of its most elegant regulars, Beirut, to play an outdoor gig. The Santa Fe, N.M.-reared Balkan folk-rock band turned a bit poppier and bubblier on last year's album, "The Rip Tide," which may have hurt its cred a bit in the indie-gloom realm but made its live shows more suitable to a fun summer bash. Opening act Little Scream is the stage name of Iowa native Laurel Sprengelmeyer, who's now based in Montreal and earning a buzz with her dramatic indie-folk debut for the Secretly Canadian label. (7 p.m. Sat., Cabooze Plaza. All ages. $25.) Chris Riemenschneider
Texas troubadour Lyle Lovett has performed scores of concerts in the Twin Cities since 1987, but this weekend will mark not only his first outdoor performance here as a headliner but his first in the area with His Acoustic Group. They're some of the same pickers from His Large Band but the texture, tone and harmonies will feel different. This group plays on some cuts on Lovett's current album "Release Me." (7:30 p.m. Sat., Minnesota Zoo, $56.) Jon Bream
Electric Guest has a lot of friends in high places. Omnipresent producer Danger Mouse helped steer the spacey Los Angeles pop duo's May-released debut for Downtown Records, "Mondo," and singer Asa Taccone helped create some of his brother Jorma's many musical projects with Andy Samberg for "Saturday Night Live." That's right, dude had a hand in "Dick in a Box." That may help explain Pitchfork's laughing review of "Mondo" (4.6 rating), but at least the Motown-copping, falsetto-laden single "This Head I Hold" has been taken seriously at 89.3 the Current and other hip outlets. BNLX and Crisis Line open. (9 p.m. Sat., Triple Rock. $10.) Riemenschneider
The mastermind behind many a dark, haunting tune, London's Coki has played a pivotal role in dubstep's development. A member of the Digital Mystiks and co-founder of the influential label DMZ, he no longer strictly spins dubplates but continues to craft lurking tracks attuned to DMZ's "meditate on bass weight" creed. This show serves as a pre-party for TC Dubstep's Infrasound Festival Aug. 2-4 in Houston, Minn. (9 p.m. Sat., Loft at Bar Fly, 18-plus, $15-$20.) Rietmulder
After dropping one of last year's most underrated local albums, synth-pop minimalists Claps are back with a seven-track cassette. Offering fewer danceable moments, "Glory, Glory" feels like a somber sidecar to the trio's full-length, with a pristinely bleak analog synth bed for frontman Patrick Donohoe to spread his emotive tenor across. Claps' magic lies in the synergy between the music's disaffect and Donohoe's Robert Smith-channeling vocals, which tug heartstrings with a shrug. In a nutshell, "Glory, Glory" has the mood of a post-prom breakup circa 1984. (9:30 p.m. Sat., Hexagon Bar, no cover.) Rietmulder
Two veteran Minnesota Zoo bands from different ends of the Latino rock realm will combine for what could be the zoo's rowdiest, wildest show of the season. The Tex-Mex, blues-rocking Los Lonely Boys -- best-known for the 2004 radio staple "Heaven" -- boast Texas' biggest guitar hero since Stevie Ray Vaughan, Henry Garza. The hip-hop-spiked, funk-blasting Los Angeles party band Ozomatli has its own Lone Star-sized reputation after being arrested during the South by Southwest festival a few years back for creating what Austin police called a street riot. That they were invited back for a free outdoor gig this year speaks volumes. (7:30 p.m. Sun., Minnesota Zoo amphitheater. $53.) Riemenschneider
