This was Rollins' last album before industry pressures led him to take a six year hiatus. The album represents one of his more notable experiments with free jazz, and according to The New Grove Dictionary of Jazz illustrates "the furthest extent to which he incorporated noise elements into his playing". Music journalist Piero Scaruffi praised the album for the dissonant titular song, "a bold thematic improvisation on the riff of Lionel Hampton's 'Hey Baba Rebop'."
