POP/ROCK
Ringo Starr always emanates joy — joy in making music, joy that he's still in the game, joy in spreading peace and love. The almost-forgotten Beatle released another joyful solo album, "Postcards From Paradise," this year. It doesn't break any ground, but it was recorded with many of the players who are on tour with His All-Starr Band — Todd Rundgren, Richard Page of Mr. Mister, Steve Lukather of Toto and Gregg Rolie of Santana and Journey. (8 p.m. Fri., State Theatre, $83.50-$154.) Jon Bream
The Sword got its big break back in 2008-09 when Metallica hand-picked it as a tour opener. Since then, the Austin, Texas-based band has been bouncing between the die-hard metal circuit and more mainstream festivals such as Bonnaroo, where its nonkitschy, nonhipstery brand of throwback stoner rock has proved its mass appeal. The quartet is back after a long break with another monstrous album, "High Country." Kadvar and All Them Witches open. (8 p.m. Fri., Mill City Nights, $17-$20.) Chris Riemenschneider
Two long-lost bands of the '80s metal era who were better than their Aqua Netted looks suggested are being dug up to mark suburban-rock mainstay Pickle Park's 10th anniversary on back-to-back nights. GNR-flavored Texas hell raisers Dangerous Toys, who had a minor hit with "Teas'n, Pleas'n," are making a rare trek north to perform Saturday with Pretty Boy Floyd opening. Coming from halfway around the world, well-regarded Japanese quartet Loudness will land Sunday with most of its heyday-era lineup intact, including masterful shredder Akira Takasaki. (8 p.m. Sat., $20-$30; 8 p.m. Sun., $20-$25, Pickle Park, 7820 University Av. NE., Fridley.) Riemenschneider
Last seen with Ringo Starr and His All-Starr Band, saxophonist/keyboardist Edgar Winter has plenty of his own songs to do. Besides the hits "Free Ride" and "Frankenstein," he has 17 albums' worth of material to draw on. Plus, he's been known to throw in a rock classic such as "Jumpin' Jack Flash" or "Rock and Roll, Hoochie Koo." Opening is Little Man, a local musician working solo electric this time. (7 p.m. Sat., Dakota, $45-$75.) Bream
When veteran singer-songwriters Lyle Lovett and John Hiatt take the stage together, the only plan is who sings first. Then it's freewheeling as they alternate songs, fire off quips, review each other's work and essentially say whatever pops into their minds. The conversation is as entertaining and satisfying as the music — and they always seem fresh in this alternative to their main gigs with their separate bands. (8 p.m. Sat., State Theatre, $48.50-$79.) Bream
With its lush, space-twangy guitar parts and ex-Galaxie 500 frontman Dean Wareham's sophisticated art-pop songwriting style, Luna was unlike any other band in the great alt-rock boom of the early '90s — and really, there's still no one like it. The quartet is known for at least one modest radio hit (1994's "Tiger Lily") and one classic album (1995's "Penthouse") and was usually a strong charmer in concert, too. After a decade of performing as the duo Dean & Britta, Wareham and his wife, bassist Britta Phillips, have put the old band back together. Foxygen band member Diane Coffee opens. (8 p.m. Sat., Cedar Cultural Center, sold out.) Riemenschneider
Nelson, twins Gunnar and Matthew, are best known for their No. 1 hit "(Can't Live Without Your) Love and Affection" in 1990 and their long blond hair. The hairdos and hit are history. Actually, their current stage show delves further into family history as the brothers sing the songs of their late father, Ricky Nelson. In the late 1950s and early '60s, he had a string of hits — "A Teenager's Romance," "Travelin' Man," "Hello Mary Lou" — thanks to his appearances on his parents' TV show, "The Adventures of Ozzie and Harriet." You'll get a new impression of Nelson and Ricky from this tribute show. (3 p.m. Sun., Ames Center, Burnsville, $42-$62.) Bream
Originally from Whitewater, Wis., New England resident Jeffrey Foucault is an under-the-radar Americana singer-songwriter who deserves more attention. His 10th album, "Salt as Wolves," was recorded at Pachyderm in Cannon Falls, Minn., with guitarist Bo Ramsey, ex-Morphine drummer Billy Conway and others. It's a collection of minimalist, atmospheric blues that sounds like a cross between Bruce Springsteen's "Nebraska" and Jamey Johnson's less twangy stuff. It's slow, sometimes smoldering and always deeply poetic whether Foucault is singing about love, loss or God. Opening is Nashville singer-songwriter Caitlin Canty. (7 p.m. Sun., Dakota, $30.) Bream
