The Three Sounds (also known as The 3 Sounds) were an American jazz piano trio that formed in 1956 and disbanded in 1973. The band formed in Benton Harbor, Michigan, United States, as the Four Sounds. The original line-up consisted of Gene Harris on piano, Andrew Simpkins on double bass and Bill Dowdy on drums, along with saxophonist Lonnie "The Sound" Walker, who dropped out the following year. The group moved to Washington and then New York, where, as the Three Sounds, they cut a record for Riverside Records, before signing an exclusive contract with Blue Note.
