by Scott YanowAt the time that this Mainstream LP was recorded, Blue Mitchell was the featured trumpeter with John Mayall's blues group. Mayall returned the favor for Blue's set, playing harmonica with an electric octet headed by Mitchell. Among the sidemen are Herman Riley (on tenor and flute), keyboardist Joe Sample and guitarist Freddy Robinson. The material (all obscure originals) is primarily blues-oriented, and the music overall is listenable and funky, but not particularly memorable. Just an average date from these fine musicians.
