POP/ROCK
Like fellow Boston alt-rock trio Dinosaur Jr., Buffalo Tom has issued its first record since the '90s and sounds as if it never went away. Titled "Three Easy Pieces," the disc recaptures the band's fuzz-pop glory and melancholic mayhem, which were always as impressive onstage as on record. About the only difference now is that frontman Bill Janovitz sounds a little more weathered and weary, though in a charming way. Blame it on his day job as a real estate agent. Climbing back in the van with a rock band will probably pay better this year. Local newcomers Western Fifth and Sounds Under Radio open. (9 p.m. today, First Avenue. 18 and older. $15.) (C.R.)
One of the nice things about the Dark Star Orchestra is you always know what to expect, but you can never expect it to be like the last time. For 10 years (and 1,500 shows), the world's favorite Grateful Dead cover band has always picked out a specific concert from the vast Dead vaults and played the set list as-was, but with at least a little more sobriety. One legitimate new thing on this tour is the addition of keyboardist Rob Barraco, who has played with Phil Lesh & Friends. (7:30 p.m. Mon., Guthrie Theater. $25.) (C.R.)
They were big in the '90s and early '00s: Alanis Morissette brought angst-ridden girl rock into the mainstream with 1995's Grammy-dominating "Jagged Little Pill," and Matchbox Twenty elevated mainstream rock to new heights with a series of benign hits including "3 A.M." and "Unwell." Last year, Morissette proved her artistic acuity with a hilarious video sendup of Black Eyed Peas' "Humps," and she promises to preview her spring CD, her first studio effort in four years. Last fall, MB20, now trimmed to a quartet, released a hits package, "Exile on Mainstream," that included six new songs that show progress in a mainstream kind of way. Opening is MuteMath. (7 p.m. Mon., Xcel Energy Center, $40-$75, 651-989-5151.) (J.B.)
Jason Isbell started 2007 as "that third-string guy in the Drive-by Truckers," but he rightfully wound up making many year-end lists with his solo debut, "Sirens of the Ditch." The country-ish rocker is back on tour with his Muscle Shoals-reared band the 400 Unit, newly featuring Son Volt member Derry De Borja. He's co-headlining with Nashville songwriter Will Hoge, out supporting his latest album, "Draw the Curtains." Kentucky's Dawn Landes, newly signed to the hip Cooking Vinyl label, also performs. (8 p.m. Wed., Varsity Theater. 18 and older. $15.) (C.R.)
In concert, British pop superstar Mika comes across like a one-man Scissors Sisters. That works in England, where he had four huge hits in 2007, and the rest of Europe. Mika (ME-ka) recently won three World Music Awards, including best new artist. Although he's nominated for a Grammy for dance recording, the 24-year-old piano popster can't seem to get arrested in the States. Is his colorful, sinfully melodious music too gay for the U.S.A.? The Midway State opens. Read an interview with Mika in Monday's Source section. (7 p.m. Wed., First Avenue, $25.) (J.B.)
BLUES At 82, B.B. King may be the hardest-touring guitarist in the business. He's making his third Twin Cities appearance in 15 months. The past two times, the legend was as much a court jester as king of the blues. But his personality is as forceful and fun as his guitar, Lucille. (7:30 p.m. Tue., Mystic Lake Casino, Prior Lake, $47-$69, 651-989-5151.) (J.B.)
DANCE/HIP-HOP If turntablists can be compared to guitarists, then the pairing of California pioneers DJ Shadow and Cut Chemist would be like Frank Zappa touring with Eddie Van Halen. Shadow's an oddball genius who's a marquee name in his own right, while Cut Chemist is a flashy, punchy mixer known for his work with Jurassic 5 and Ozomatli. The old friends are touring with eight turntables and four mixers in keeping with their third collaborative disc, "The Hard Sell," on which they used 7-inch, 45-rpm records instead of the usual 12-inchers. The results are a terrific mish-mash of soul, funk, mind-warping techno and pure kitsch. Canadian wiz Kid Koala opens. (9 p.m. Mon., First Avenue. 18 and older. $20.) (C.R.)
COUNTRY Tracy Lawrence, a 1990s mainstay, returned to the top of the charts last summer with "Find Out Who Your Friends Are," featuring friends Tim McGraw and Kenny Chesney. That tune earned them a trophy for musical event of the year at the Country Music Association Awards -- Lawrence's first CMA prize. (8:30 p.m. today, Medina Entertainment Center, $25-$42, 763-478-6661.) (J.B.)
