Three sides of Charles Mingus in this remastered reissue set: the 1961 Candid album Mingus Presents Mingus with the classic quartet of Eric Dolphy, Ted Curson and Dannie Richmond; then the Mercury release Pre-Bird from the same year, in ensembles performing the music of or influenced by Duke Ellington, along with the ambitious and brilliant through-composed work, "Half Mast Inhibition".
