Mingus Dynasty, like its predecessor and Columbia companion Mingus Ah Um, was recorded in 1959, a watershed year for the insuperable, eruptive bassist-composer Charles Mingus. Leading what amounted to a repertory company comprising some of New York's best and most creative improvisers, Mingus musically challenged two ensembles as they'd never been challenged before. The music herein remains as arresting as the LP's original cover photograph of a mock-imperious Mingus in full Chinese emperor regalia was eye-catching.
