Mr. Bungle. 1st album was crazy, but funky as hell with lots of brass. 2nd is a UFO (a great one, but definitely harder to listen to from the beginning to the end).
Introduce Yourself was Faith No More’s second album. We Care A Lot was first, and there wasn’t a radical change between the two.Faith No More - 'Introduce Yourself' to 'The Real Thing' was a huge step up replacing Chuck Mosley with Mike Patton.
Jane's Addiction - S/T debut wasn't so much an album as it was a compilation with a mix of live and studio tracks. 'Nothing's Shocking' followed and that was a major improvement for them as far as their sound and songwriting.
Stone Roses - first album was chimey powerpop.
2nd album was Led Zep wannabe.
