In a review for AllMusic, "Blue" Gene Tyranny called the album "probably the first recording of improvised jazz combined with electronic music, as well as playing inside the piano and other new music techniques," and noted that it "contains lively and often humorous compositions."[1]
The authors of The Penguin Guide to Jazz Recordings wrote: "This is an intriguing period piece, which has considerable staying power... It's important for the integration of electronics into a basic piano trio, and while it's callow in its way it continues to intrigue."[5]
Clifford Allen of All About Jazz stated that James "more than acquits himself as a free player," and commented: "rare indeed is a successful pairing of electronic and acoustic audio collage, much less in a mid-1960s jazz setting."[8]
Writing for Aural Innovations, Doug Walker remarked: "the music explodes with both vitality and subtle introspection... throughout there is a spirit of discovery that's quite refreshing, and the sense of musical optimism pervades the recording!"[9]
