David Eugene Lewis (1938 – March 13, 1998) was an American rock and rhythm & blues (R&B) keyboardist, organist, and vocalist based in Seattle, Washington, US.

The family moved first to seek work in the navy town of Bremerton, Washington, across Puget Sound from Seattle, where they settled in the segregated Sinclair Heights housing projects.

Lewis tried both guitar and piano, but gravitated toward the latter, especially after hearing Ray Charles,[3] who was launching his performing career in Seattle in the late 1940s.

[3] In the summer of 1956, Lewis still had one more year to complete at Seattle's Franklin High School, but his combo was the hottest item in the region.

This led to similar opportunities with Ray Charles, Little Richard, Jerry Lee Lewis, the Platters, Ike and Tina Turner, the Drifters, Roy Orbison, and Gene Vincent and his Blue Caps.

Lewis's combo became the first African-American band to play frequently on traditionally white turf, including downtown clubs, University of Washington fraternities, and even suburban venues.

[3] Shortly after the end of the fair, Lewis switched from piano to Hammond B-3 organ, and formed a new trio with guitarist Joe Johansen and drummer Dickey Enfield (who would be replaced in 1966 by Dean Hodges).

[3] His new trio scored minor hits with "David's Mood (Part 2)" (1963) and "Little Green Thing" (1964), both of which were heavily covered by other Pacific Northwest bands.
