Jeff Porcaro (April 1, 1954 – August 5, 1992) was an American drummer, songwriter, and producer, widely regarded as one of the most talented and influential drummers in the history of popular music. Known for his precision, musicality, and subtle groove, Porcaro was a master of feel and timing. His style was deeply rooted in rock, pop, jazz, funk, and R&B, making him one of the most sought-after session drummers of the late 20th century. Born in Hartford, Connecticut, into a musical family, Jeff was the son of jazz percussionist Joe Porcaro.

He grew up in Los Angeles and began playing professionally as a teenager. By age 17, he was already touring with Sonny & Cher, and soon after became a key session player in L.A.’s vibrant recording scene. In 1977, Jeff co-founded the band Toto with his brother Steve Porcaro, David Paich, Steve Lukather, and others. With Toto, he helped create a string of hits, including "Hold the Line," "Africa," and the Grammy-winning "Rosanna" — the latter featuring his legendary "half-time shuffle" groove, which has since become a benchmark in drumming technique. Aside from his work with Toto, Jeff Porcaro's session career was extraordinary.

He played on hundreds of albums, contributing to some of the biggest hits of the 1970s, '80s, and early '90s. His drumming was known for its tastefulness, restraint, and deep pocket — qualities that made him a favorite among producers and artists alike.
