"The radio station, KING-FM, recorded the programs. Swingin' in Seattle comes from four different gigs at the Penthouse in 1966 and 1967. During this period Adderley's quintet (with brother Nat, Joe Zawinul, Victor Gaskin, and Roy McCurdy) made their hit album, Mercy, Mercy, Mercy! It was a move toward commercialism, but Adderley's live gigs were still mostly undiluted postbop. "Somewhere" is uncharacteristically sweet, but "Big P," "Sticks," and "74 Miles Away" prove that this band could make music in which intellectual depth was commensurate with greasy funk. When Adderley plays a Charlie Parker bop tune, "Back Home Blues," and smokes it, he still sounds innocent and joyful. Nat's cornet solos are sly, tart asides. As for Zawinul, no one that nasty has ever come out of Vienna, Austria".
