We woke up to the sad news today that Grant Hart lost his battle with cancer at age 56. His former Husker Du bandmate Bob Mould penned a tribute, and other musicians have been paying their respects too. See below for tributes from Mike Watt (The Minutemen), Tanya Donelly (Throwing Muses, The Breeders, Belly), Justin Broadrick (Jesu, Godflesh), Ryan Adams, Carl Newman (The New Pornographers), Craig Finn (The Hold Steady), Colin Meloy (The Decemberists), Billie Joe Armstrong (Green Day), comedian Michael Ian Black, Fred Armisen, Mac McCaughan and Jon Wurster of Superchunk, METZ, Cloud Nothings, The Meat Puppets, Frank Turner, Ted Leo, J Mascis' band Sweet Apple, and more.

We've also unearthed some never-seen photos of Husker Du playing NYC's Peppermint Lounge in 1985
