I think Soundgarden is a bit of a mix of Zeppelin and Sabbath.
Imo Cornell was probably the most talented person to come out of that era. Powerhouse singer, very good lyricist, and underrated as a guitarist. He was doing acoustic shows with just him and a guitar more towards the end there and he was just great.
The Soundgarden album King Animal which came out around 2010 fits right in with the rest of their discography.
