Jeffrey Thomas Porcaro (April 1, 1954 – August 5, 1992) was an American drummer and songwriter. He is best known for being the co-founder and drummer of the rock band Toto, but is also one of the most recorded session musicians in history, working on hundreds of albums and thousands of sessions. While already an established studio player in the 1970s, he came to prominence in the United States as the drummer on the Steely Dan album Katy Lied (1975).
