This is an LP reissue of a set that was originally titled Pre Bird because it features some of the advanced originals that Charles Mingus wrote prior to hearing Charlie Parker.
The bassist leads an undisciplined but colorful 25-piece orchestra on three titles including an Eric Dolphy feature on "Bemonable Lady" while the other five tracks are by a ten-piece (including two pianos) band; Lorraine Cousins sings "Eclipse" and "Weird Nightmare." It's an interesting set of typically unconventional music by Mingus.
