Jackie Davis

Jackie Davis was an American soul jazz singer, organist and bandleader. He is notable for his contributions in bringing the Hammond organ to the forefront of jazz and pop, preceding the betterknown Jimmy Smith by several years.

Davis was born and grew up in Jacksonville, Florida, and started playing piano at the age of ten, before studying music at Florida AampM. He experimented with jazz on the pipe organ, before switching to the Hammond. He was influenced by Wild Bill Davis and Bill Doggett, and after a spell backing Louis Jordan, he started fronting his own jazz groups.
