The End Of An Ear (1970) - rating: ****
An early instrumental album. Jazz prog rock. I love it

Rock Bottom (1974) - rating: *****
Absolute the best from Robert. All songs are great and songs are following each other non-stop.

Ruth Is Stranger Than Richard (1975) - rating: ***
A step backward from the highly successful Rock Bottom.

Nothing Can Stop Us (1982) - rating: ****
Not a real studio album but a compilation of exclusive singles from the early 80's. Includes a terrific Chic cover: "At Last I Am Free"

Old Rottenhat (1985) - rating:  ****

Dondestan (1991) - rating: ****

Shleep (1997) - rating: *****
His best album of the 90's
