These are the Adderley brothers, Cannonball and Nat, respectively on alto sax and cornet, and both at the head of a top flight quintet featuring Mr. George Duke on piano (acoustic and electric), Walter Booker - bass and Roy McCurdy - drums. Recorded live in Vienna on November 4, 1972, this is a fine example of pure electric jazz-funk of the era. The album opens with an ecstatic twenty minutes long version of George Duke's 'Black Messiah' and it goes on with equal intensity throughout five other tracks including 'Hummin',' 'Soli Tomba' and three Joe Zawinul classic gems, 'Directions,' 'Mercy, Mercy, Mercy' and 'The Scene.'
