As if marking the 20th anniversary of his biggest-selling album weren't enough for one tour, Bob Mould just released one of his best records yet.
"I knew if I went out on the road only to play 'Copper Blue,' I was probably going to burst," said the blunt-speaking Twin Cities rock alum, who'll perform that disc in its entirety Saturday at First Avenue with his latest trio.
"Copper Blue," by Mould's short-lived power trio Sugar, is one of the most concise, ageless, perfect records of the alt-rock era of the early '90s -- a wave that Mould, 51, helped ripple to life with his St. Paul-reared group Hüsker Dü. The album, which sold about 300,000 in its original incarnation, earned a deluxe-edition reissue in July on Merge Records, the indie label behind Arcade Fire and Spoon.
But that's not all he'll play Saturday night. Merge also just issued the new album "Silver Age," Mould's hardest-blasting effort since his Sugar days.
He recorded it with his new bandmates, bassist Jason Narducy (formerly of Verbow) and drummer Jon Wurster (Superchunk) following what he called "a perfect storm" that led to a faster and feistier album.
"I had these moments while making it where I was thinking, 'Am I copying myself here?' or, 'Is this too influenced from hanging out with the Foo Fighters?'" Mould recounted. "Finally, I was like, '[Screw] it. Just go with it.'"
Two years ago Foo Fighters frontman Dave Grohl, a longtime fan, recruited Mould to sing on "Dear Rosemary," a highlight of the band's Grammy-winning 2011 album. That led to appearances with the Foo crew, including a Mould tribute concert last fall in Los Angeles that also featured Ryan Adams, Ben Gibbard and members of the Hold Steady.
Those rocking affairs were sharply contrasted by solo gigs and reading engagements to promote his 2011 autobiography, "See a Little Light: The Trail of Rage & Melody," in which he opened up about his anger issues, his coming out as a gay man and the many facets of his 33-year music career.
