Spencer Davis, born Spencer David Nelson Davies on July 17, 1939, in Swansea, Wales, was a renowned musician best known for founding the Spencer Davis Group. He began his musical journey at a young age, learning the harmonica and accordion, influenced by his uncle. Davis attended Dynevor School in Swansea and later studied German at the University of Birmingham. His early musical influences included skiffle, jazz, and blues, and he was inspired by artists like Big Bill Broonzy and Buddy Holly.

In 1963, Davis formed the Spencer Davis Group in Birmingham with Muff and Steve Winwood and drummer Pete York. The band achieved significant success in the 1960s with hits like "Keep On Running," "Somebody Help Me," "Gimme Some Lovin'," and "I'm a Man," the latter two co-written by Davis and featuring Steve Winwood's vocals. The group was known for their energetic soul and R&B sound.

Despite feeling overshadowed by Steve Winwood's prodigious talent, Davis was recognized for his ability to assemble talented musicians. After the Winwood brothers left the band, he continued to lead the group, releasing the single "Time Seller" and the album "The Spencer Davis Group With Their New Face On" in 1968, before dissolving the band the following year.

Davis later worked as an A&R executive with Island Records. He passed away on October 19, 2020, in Los Angeles, California, leaving behind a legacy as a pivotal figure in the British rock and rhythm and blues scene.
