Here's an idea and a half: halfway though Sam Chennault's Atmosphere profile, Slug mentions that he's working on a covers album: Slug Does Women, where he covers Liz Phair, Alanis Morrissette, and Shellac, because "Steve Albini is a bitch." Probably never going to see the light of day (nor is it probably even really in the works), but I'd listen to it once.
