Twennynine featuring Lenny White was an influential American funk and jazz fusion band of the late 1970s and early 1980s. The group was formed by legendary drummer Lenny White, a former member of the pioneering jazz fusion group Return to Forever. Twennynine's music blended elements of funk, R&B, and jazz, and they are perhaps best-known for their hit single "Peanut Butter". Their innovative sound and White's established reputation in the jazz world made a significant impact on the evolution of fusion music.
