Changes One is an album by the jazz composer and bassist Charles Mingus, released in 1975.

This track is dedicated to the Attica Prison Riots of 1971 and the Governor of New York State at that time, Nelson Rockefeller.

The lyrics are by Clarence “Gatemouth” Brown, but the melody is newly composed by vocalist and saxophonist George Adams.

Mingus also has composing credits, possibly for the horn lines that follow the singing.

All compositions by Charles Mingus except where noted.
