In the Slot

In the Slot is a Tower of Power album released in 1975. It was their last studio album for Warner Bros. Records. It also marked the debut of new vocalist Hubert Tubbs. David Garibaldi returns to the drummer's throne after being absent from the previous album Urban Renewal (save for one track), although the drummer from that album, David Bartlett, does appear as a background vocalist on this album, as does Garibaldi's next successor, Ron Beck. "Ebony Jam" and "Drop It in the Slot" were sampled on the Beastie Boys' 1989 album Paul's Boutique.
