This has been posted before but I'm going to post it again because Eyehategod is one of the seminal sludge bands, and Mike IX is in dire need of a liver and may not be with us much longer. I think this performance defines the genre: Mike's voice is fucked, Aaron is fucked up, and Jimmy just fucking rocks.
Sometimes I put 30 minutes away just to listen to this song in its entirety. I don't care how awful the quality, this live version is the most intense song I've seen on youtube and I'm fucking glad it exists.
