Irrespective of his personal habits, he was a great musician and was at least partly responsible for the "invention of Rock and Roll"
Here's something I wrote on Zerogain over a week ago.
Ike Turner - The inventor of Rock & Roll
Thought of by many to be just the violent, drug using ex-husband of Tina Turner. He has paid for his errors but he did help to invent Rock and Roll.
He built up a strong reputation in R&B being an excellent bandleader and musician. His band, Kings of Rhythm built up a good reputation. In the early 50's, they recorded with Sam Philips of Sun Records fame.
Ike Turner wrote a song called Rocket 88. This was sung by one of his sax players, Jackie Brenston. The tune was based around a late 40s song called Cadallac boogie. It was also based on a song called Rocket 88 boogie. Ike made his tune more raw, adding a strong backbeat. He took strong elements fro the jump blues and swing that was big at the time. He played piano on the recording. His panio intro was later copied by Little Richard on "Good Golly Miss Molly". The record features an early example of the distorted guitar sound that is so loved in popular music.
For some reason the record came out as "Jackie Brenston and his Delta Cats" with no writing credit for Ike Turner. The record was a smash hit and was covered a few months later by Bill Hailey.
Jackie left the band & Ike carried on. He later meet Tina turner and that's another story.
There are other artists and records that could have the claim of the first rock & roll record but alot of people point to this one.
