BLUES
With Clapton swearing off the road and B.B. reduced to shtick, Buddy Guy is probably the blues' most famous ambassador these days (nope, John Mayer doesn't count). Guy can also be a little too showy at times, but he still packs a wallop as a guitar player and howler at age 78. And if for some reason the Chicago legend doesn't deliver, his tourmates Robert Randolph & the Family Band always pack enough bang for two bands with their funky, gospel-ized, steel-guitar-led brand of blues. (7 p.m. Sun., Orpheum Theatre, $48.50-$58.50.) Riemenschneider
POP/ROCK
The last installment in what could probably be declared the best year ever for live music in Mears Park, the Concrete & Grass Festival returns with its usual eclectic mix of homegrown talent. Forty-member vocal ensemble the Prairie Fire Lady Choir, which debuted powerful original songs at the start of summer, headlines Friday's lineup along with Latin dance vets Salsa de Soul and the jazzy Adam Meckler Orchestra. The Twin Cities' resident British rock legend, Badfinger's Joey Molland, tops off Saturday playing hits such as "No Matter What" and "Baby Blue," preceded by a Minnesota Opera showcase, Breaking Brass and the Ancia Saxophone Quartet. (5:30-10 p.m. Fri., 4-10 p.m. Sat., Mears Park, downtown St. Paul, free, ConcreteandGrass.com.) Chris Riemenschneider
Meet the new Jayhawks, same as the old Jayhawks — but not the original Jayhawks. Gary Louris once again takes front and center in Minnesota's beloved country-rock band, just as he did in 1997 when co-leader Mark Olson quit the group. He's back with the "Sound of Lies"-era lineup touting a reissue of that cathartic album and the two that came after it, with Kraig Johnson of Run Westy Run and Golden Smog on guitar, keyboardist Karen Grotberg and the standard rhythm section of Marc Perlman and Tim O'Reagan. Brit-rocky locals Two Harbors open the first show, and Milwaukee's Trapper Schoepp is on for the second night. (8:30 p.m. Fri. & Sat., First Avenue, $30.) Riemenschneider
Since her divorce album "Interiors" in 1990, Rosanne Cash has made art, not hit songs. One of her masterworks is the new "The River & the Thread," a deeply ruminative and elegant rhapsody on her Southern roots. Those tunes will be the focus of her current tour but she'll always sing her signature "Seven Year Ache." Read an interview with Cash at www.startribune.com/music. (8 p.m. Fri., the O'Shaughnessy, St. Catherine University, St. Paul, $40-$60.) Jon Bream
The dedicated archivists at Sundazed Records recently gave local 1960s rock heroes Crow the deluxe reissue treatment, putting out both CD and vinyl editions of "The Best of Crow," with intriguing bonus cuts. There's an unreleased demo of the boys covering the Beatles ("When I Get Home"), an extended version of their hit "Cottage Cheese," plus the epic "Evil Woman" — covered by both Black Sabbath and Ike & Tina Turner — along with "Don't Try to Lay No Boogie Woogie on the King of Rock and Roll" and anything else you might remember from this fine group that toured with Janis Joplin and rivaled Steppenwolf with their gritty power. Three original members — singer Dave Wagner, songwriter/bassist Larry Wiegand and keyboardist "Kink" Middlemist — are still flying high, joined by guitarist Jeff Christensen and drummer Norm Steffen. (9 p.m. Fri., Famous Dave's Uptown, $8.) Tom Surowicz
Already familiar to local Deep Blues Fest attendees, Alabama's gritty, blaring Southern rockers Lee Bains III & the Glory Fires have since been signed to Sub Pop Records and just released one hellacious album for the famed Seattle label, "Dereconstructed." Memphis-reared singer/songwriter John Paul Keith, who's part Nick Lowe and Eddie Cochran, also made a name for himself locally with a recent set on the "Real-Phonic Radio Hour." Hometown hell-raisers Eleganza! also perform. (9 p.m. Sat., Turf Club, $10-$12.) Riemenschneider
A reminder that bearded locavores and hipster vegans aren't entirely new to Uptown, the Wedge Co-Op's 40th Anniversary Block Party boasts an impressive array of musicians who've shopped and/or worked at the natural-foods store. Americana stalwarts the Pines, acoustic folk vet Spider John Koerner and twang man Erik Koskinen suit the co-op's rootsy flavor, but hip-hop maven Maria Isa and innovative electro-looper Dosh will also be there to represent its progressive side. (Noon-6 p.m. Sun., 2105 Lyndale Av. S., Mpls. all ages, free.) Riemenschneider
A daytime gathering of local tribute bands made up of musicians who moonlight in original bands, Cover Me Impressed will boast a Van Morrison set (by Terry Walsh's Belfast Cowboys), Guns 'N Roses (Appetite for Zaccardi with Romantica's Tony Zaccardi), the Pixies (Trompe le Monde), Hall & Oates (Private Oates with BB Gun's Al Church), Thin Lizzy (Jailbreak!) and the Kinks (Kinda Kinky) — but not a full-fledged Replacements tribute, although Melismatics leader and new dad Ryan Smith will kick it off with an all-Minnesota set sure to feature a little 'Mats. The door money benefits Epilepsy Foundation of Minnesota. (1-9 p.m. Sun., Harriet Brewing, $12 suggested donation.) Riemenschneider
