I don't know the "greatest band" is, or was, but Ike Turner is, according to Little Richard and a lot of other people the real Father of Rock and Roll - and this all happened before he even met Tina. He's still going strong.

Ike's Music, His-Story
Ike's contribution of music is quite extensive. Not only has Ike collaborated with many well known artists in the R & B and Blues industry, Ike also contributed his unique styling in Rock & Roll and Hip Hop as well.

Many do not know that Ike's musical influence and prominence predates the duo that brought his musical talent to the limelight. Starting with Sun records and writing the "First Rock & Roll" song "Rocket 88" Ike had established his musical abilities way back to when Elvis was just a kid.

Ike's music has garnered him a place in the Rock & Roll Hall of Fame and well as a nomination for a Grammy Award to winning W.C. Handy Awards, "Walk of Fame Star" as well as a" Beal Street Music Note"

VH1 Quote "Ike Turner is one of the Musical legends of the period, and some of his background work in the 60's should be seen a crucial to the development of R&B."
