Power-pop favorites The Posies currently are out on a 30th anniversary tour, and the band’s stop in St. Paul, Minn., on Tuesday night featured an extra treat: The group brought Hüsker Dü bassist Greg Norton onstage during the encore to rip through four of that band’s classics. See video of their performance right here.

Minnesota Public Radio’s The Current has just  launched a five-part documentary podcast series called “Do You Remember?” that promises to trace the formative years and legacy of Hüsker Dü through interviews with those who were there as well as the three band members themselves — including Grant Hart.

Grant Hart, the founding drummer who served as co-songwriter/singer for pioneering hardcore-punk trio Hüsker Dü, a band that laced tuneful melody with blistering power to help define the ’80s indie scene, died overnight at the age of 56, the Minneapolis Star Tribune reports. He had been diagnosed with cancer.

After dropping hints for months, Numero Group today finally revealed full details of their multi-disc Hüsker Dü box set Savage Young Dü, which collects new remasters of the punk/hardcore trio’s entire studio output from 1979 to 1982 — including 47 unreleased tracks. See the full tracklist here.

The Hüsker Dü catalog famously has been in dire need of a sonic upgrade and expansion, and it seems, at long last, that it’s happening, courtesy of the Chicago-based reissue pros at the Numero Group, who are assembling something “massive” around the band’s archives.

This week’s new releases include new albums from Sinead O’Connor, Cocksure (Chris Connelly) and Stiff Little Fingers, box sets from John Foxx and Suzanne Vega and the documentary “Every Everything: The Music, Life and Times of Grant Hart.”
