“No jaded jazz, this. Few contemporary combos top the Mingus Quintet in the art of creating new, round cool sounds. Working from a musical skeleton, Charles Mingus spontaneously makes music related to the moment. Mingus at the bass is strictly off-the-record, a jazzophile's dream. Ah um, yes, experimental mile-high music that's solace for your soul. Go oh ah with Mingus today.”

From an ad that appeared in the October 1959 issue of DownBeat Magazine promoting MINGUS AH UM.
