If you like blues-rock with guitar solos, Roy recorded some high quality material. Some people don't like that style, which is fine with me!
Roy went on and recorded some excellent albums through 1987. His later albums were on the blues label Alligator Records. He had some good vocalists with him on some of his later material. I have explored a lot of his recordings and they are consistently good to excellent from the early 1970s to 1987.
Reportedly he had gained control of his drinking and was doing well, when he relapsed and was arrested for public intoxication after a domestic dispute. He hung himself in his cell in the Fairfax County, Virginia jail in August, 1988, He was 48 years old.
Years later i drove past the Fairfax County, Virginia jail. It is in a beautiful high income looking area. The entire situation is very sad.
That is a fine anthology of his work, but I need more by him. I have heard a lot more of his albums, and they left some great stuff out.
