I'm very surprised nobody mentioned Raw Power yet!
Who in the hell had the awesome idea to record Ron Asheton's bass and James Williamson loud ass guitar on the same track? (probably super coked out David Bowie) This made the bass pretty nonexistent in the louder songs. Despite all this, it's one of my favorite albums ever. The reissue did make it sound better.. but there were mistakes made here that couldn't be repaired.
