By The Grace of God & High Visibility by 'Copters. Great albums, but you rarely (as in never) hear people talk about them.

The Verve's second album "A Nothern Soul", very sad music and a captivating listen.
 
Procol Harum's first album, self titled which impressed me rather unexpectedly. Accessible and layered at the same time.
 
Kyuss in general, I could live without my Metal and Hard Rock albums but from the first time I listened I just liked Kyuss and I still listen to Kyuss tracks every once in a while.
 
Chicago in general, combine a Rock/Pop band with a horn section and make it swing. These guys were good.
 
This is just a list of some examples in an seemingly endless list of forgotten and ignored music...
