John Voorhis "Tim" Bogert III was an American musician. As a bass guitarist and vocalist he was best known for his powerful vocal ability and his fast runs, fluid agility and ground-breaking sound on his Fender Precision bass. He was one of the pioneers of using distortion with his bass to help it cut through the mix with the low-powered amps of his time which also imparted a very sharp-edged sound to it. He was a frequent collaborator with drummer Carmine Appice; the duo performed in such bands as Vanilla Fudge, Cactus and the power trio Beck, Bogert & Appice.

Carmine Appice is an American rock drummer. He is best known for his associations with Vanilla Fudge; Cactus; the power trio Beck, Bogert & Appice; Rod Stewart; King Kobra; and Blue Murder. He is also Vinny Appice's older brother. Appice was inducted into the Classic Drummer Hall of Fame in 2013 and the Modern Drummer Hall of Fame in 2014. He is also a more than capable (fretless-) bass player, as can be heard on the "Guitar Zeus" albums, for example.
