On March 27, 1969, the group shared the stage, with Phil Woods & His European Rhythm Machine playing first. That evening, Cannonball had the unfortunate surprise of hearing voices from the audience filled with disapproval. The CD reflect this displeasure at the end of Black Orpheus and when Mercy, Mercy, Mercy is introduced. Actually, there was a very serious misunderstanding between Cannonball and the audience, or at least some of the audience who had come to hear the Cannonball of the Riverside period and tunes such as This Here, Hi-Fly, Unit 7, while he had decided to play the repertoire from his most recent Capitol records, with pieces such as Walk Tall , Mercy, Mercy, Mercy, and Experience In E. That having been said and notwithstanding the misunderstanding in 1971, the Adderley brothers group was excellent unit, capable of showcasing the leader's virtuosity as a verbose, convincing and natural improviser, Nat Adderley's, solos as a skilled explorer of harmonic webs with powerful eloquence, Joe Zawinul, who moves with confidence in this environment which he would soon leave to go and create Weather Report, Vic Gaskin, more solid as an accompanist than as an inventive soloist, and Roy McCurdy on a drums, reminiscent of Louis Hayes with his abrasive way of playing the cymbal, were ideal partners for the Adderley brothers, for whom a good mood was was second nature.
