Shellac's also the best show I've ever seen, with Melt Banana being near the top.
I want to hear Albini produce a Sunn album now..
Also, you gotta hand it to the guy, he knows his music:
MX-80/MX-80 Sound are one of the best bands ever (and I'd say they're a band Shellac owes a lot of their sound to, though Shellac aren't as weird of course..).
