Joni Mitchell was a serious artist, chasing her muse to the four corners of the Earth. Folk songwriting? Sure, as long as the muse is there. An album of music inspired by Charles Mingus, using the jazz world’s finest musicians? As long as the muse goes there. Avant-garde next? Don’t worry about categories, chase the music.
This is one of the greatest tracks of Joni’s Mingus period, featuring the Galileo of Bass, Jaco Pastorius, not to mention luminaries such as Michael Brecker on sax on Don Alias on drums.
Who cares how to categorize it? It’s great music.
