Jeffrey Porcaro was an American drummer, songwriter, and record producer. He is best known for being the co-founder and drummer of the rock band Toto but is one of the most recorded session musicians in history, working on hundreds of albums and thousands of sessions.
AllMusic has characterized him as "arguably the most highly regarded studio drummer in rock from the mid-'70s to the early '90s" and says that "it is no exaggeration to say that the sound of mainstream pop/rock drumming in the 1980s was, to a large extent, the sound of Jeff Porcaro."
