The 3B's (also credited as The Three B's) was a jazz trio comprising Bross Townsend, Bob Cunningham and Bernard Purdie.
They recorded two albums of jazz and blues standards in the mid-1990s, both of which featured, among other sidemen, Houston Person on tenor saxophone and Fred Smith on trumpet.
The three B's (Bross, Bob and Bernard) had previously recorded together in 1985 on Bob Cunningham's only album as leader Walking Bass, and Purdie, Carrie Smith, and Bross Townsend had previously performed together at the Brooklyn Academy of Music's 100 Years of Jazz and Blues festival in 1992.
