Enshrined in the Penguin Jazz Guide's Core Collection, this quintessential platter of Sun Ra's late 1950s Chicago ensemble showcases the brilliant tenor sax stylings of John Gilmore, and introduces Arkestra mainstays Marshall Allen, Pat Patrick, and Ronnie Boykins. Recorded and issued in 1959, it marks a coda for the bandleader's bebop/hard-bop stage, as his interstellar traveler persona began to transform the band and the music. Many of the early works on these recordings would remain staples in Arkestra set lists for the rest of Sun Ra's life. Includes the complete, contemporaneous Sound Sun Pleasure LP, rare stereo mixes, and bonus tracks.
