Longtime Minneapolis guitar picker Peter Lang is best known for his acoustic virtuosity that warrants putting him in the same sentence with John Fahey and Leo Kottke. (The three of them made an unforgettable album together in 1974.) On this year's "Testament," Lang demonstrates a new persona -- singing bluesman. Joined by drummer Dave King, bassist Steve Larkin and harmonica player/producer Michael Tanner, Lang travels down the roads of his youth. He dusts off such classics as "Stackolee" and "Delia" as well as the African folk song "Guabi Guabi" with equal elan. (7 & 9:30 p.m. Sat., Dakota, $25 & $20.) (J.B.)
St. Paul's Red House Records celebrates its 25th anniversary this month with a defining compilation CD, "Our Side of Town," and a series of concerts, most notably one that teams two underappreciated acts, Lucy Kaplansky and Storyhill. A licensed psychologist, Kaplansky explores family relationships on 2007's "Over the Hills," her sixth CD for Red House. Storyhill, the duo with the pretty Simon & Garfunkel-evoking harmonies, has released one studio disc on Red House after putting out four on their own label. (8 p.m. Sat., Fitzgerald Theater, $28.50.)

The rerelease of Bon Iver's self-made, cathartic album "For Emma, Forever Ago" in February not surprisingly earned ample print praise to go with last year's blogger buzz. Now, Justin Vernon -- the Eau Claire, Wis., native behind the alias -- is gaining more raves on tour, re-creating an album that could have been quite difficult to re-create. After a sold-out tour kickoff at the Turf Club in February, he opted for two nights this time. Tickets to both shows are already gone. (9 p.m. Sat., 7 p.m. Sun., Turf Club.) (C.R.)
Throat cancer left John Prine with a ragged croak of a voice, but his songs are filled with such whimsy and wisdom that he remains a must-see. The Chicago-turned-Nashville troubadour looks at life's absurdities and revels in the pain and joy with twisted humor. His stuff from the 1970s ("Your Flag Decal Won't Get You Into Heaven Anymore," "Souvenirs") still rings as true as his recent material (2005's "Crazy As a Loon" from the very good "Fair and Square"). Don't be surprised if he throws in a few country covers from last year's collaboration with Mac Wiseman, "Standard Songs for Average People." Opening is Paul Thorn, Mississippi's answer to Springsteen, whose latest, "Long Way From Tupelo," oozes bluesy grit. (8 p.m. Sat., State Theatre, $55.50-$58.50.) (J.B.)
On record, Ontario-reared psychedelic rock troupe Caribou is mainly a one-man band (super-nerd Dan Snaith), but it really comes to life onstage, echoing the likes of Neutral Milk Hotel and/or a guitar-lite My Bloody Valentine. Snaith's herd is on tour with the F--- Buttons, a British electronic duo that earned a buzz at South by Southwest. (10 p.m. Sat., Triple Rock. $12-$15.) (C.R.)
Violin-armed New York rocker Bitch -- yep, just Bitch! -- was one of the first acts the owners of Pi Bar brought to town after opening, and now they're bringing her back with her full band, Bitch and the Exciting Conclusion. Her Patti Smith-inspired punk-poet songs have been featured on "The L Word," and she got her first bit of national fame appearing in the movie version of "Hedwig & the Angry Inch." (9 p.m. Sun, Pi Bar. 18 & older. $6.) (C.R.)
Former Toad the Wet Sprocket frontman Glen Phillips' fifth solo release is a little bit different. "Secrets of the New Explorers" is a six-track EP that explores space in a down-to-earth way. He may be singing about "Solar Flare" and "The Spirit of Shackleton" (a salute to Antarctic adventurer Ernest Shackleton), but the sounds are more universal pop than space-age rock. (7:30 p.m. Sun., Cedar Cultural Center, $18-$22.) (J.B.)
Boston guitarist Johnny A. eschews vocals and a surname, yet has done pretty well in the past decade, making some tasty CDs for Steve Vai's label. Before that, he played jazz fusion, garage rock, alt-country and backed J. Geils Band singer Peter Wolf for seven years. So his agile mix of styles -- rock, blues, jazz, Americana -- comes naturally. (7 & 9:30 p.m. Sun., Dakota. $15-$20.) (T.S.)
