Jeff Porcaro recorded the drum track for "Rosanna" at Sunset Sound in Los Angeles in December 1981. It was the second take. The song opens with two bars of drums alone — no guitar, no keys, no vocal — just Porcaro laying out the groove he'd built from Bernard Purdie's half-time shuffle, John Bonham's kick pattern on "Fool in the Rain," and a Bo Diddley beat on the bass drum, threaded through with ghost notes so light they feel more like breath than percussion. When the rest of the band enters, everything clicks into place with the ease of a door closing on a well-made frame. That opening is a statement of intent: the drummer is not keeping time, he is making the music possible.
By the time "Rosanna" became the opening track of Toto IV and won the Grammy for Record of the Year at the 1983 ceremony, Porcaro had already been doing exactly this for nearly a decade. He was born in Hartford, Connecticut, on April 1, 1954, the son of Joe Porcaro, an LA session percussionist who understood the studio economy from the inside. Jeff began playing drums at seven, left high school to join Sonny and Cher's touring band at seventeen, and by his early twenties was working on hundreds of albums. He came to wider attention as the drummer on Steely Dan's Katy Lied in 1975 — he was twenty-one years old when he recorded it — and had already played on Pretzel Logic the year before, sharing the drum chair with Jim Gordon on the dual-drummer track "Parker's Band." Fagen and Becker were not easy clients. Getting that call, and keeping it, told the Los Angeles session world everything it needed to know.
The breadth of what followed is almost disorienting to catalog. Boz Scaggs's Silk Degrees in 1976 — the record that defined the softer, more sophisticated end of the FM dial — runs on Porcaro's drums from first track to last. His "Lowdown" groove is deep-pocketed funk played with the restraint of a jazz musician; his "Lido Shuffle" beat has the bounce of a New Orleans second line filtered through a studio in Burbank. Boz Scaggs, who met Porcaro through producer Joe Wissert while assembling the Silk Degrees sessions, later described the experience with unusual precision: "He actually moved me as a singer through the song. Everybody in the band would know what was coming up in the next few bars, because we could feel it in the way he anticipated." That is the quality that made Porcaro irreplaceable: he was not reacting to the song, he was shaping it from underneath.
The session credits that accumulated across the late seventies and eighties read like a map of the entire adult contemporary landscape. Paul Simon's Hearts and Bones in 1983. Don Henley's End of the Innocence in 1989. Lionel Richie's Can't Slow Down in 1983. Christopher Cross's debut. Elton John's Jump Up. George Benson. Hall and Oates. Bonnie Raitt's Luck of the Draw in 1991. Dire Straits' On Every Street, also 1991. Pink Floyd's The Wall in 1979. Paul McCartney's Give My Regards to Broad Street in 1984, where Porcaro played on the "Silly Love Songs" version and on "The Girl Is Mine" with McCartney and Michael Jackson. AllMusic, in its assessment of his career, put it plainly: "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." The claim holds up because the records are right there to verify it.
What made the Rosanna shuffle so instructive — and why drum educators still use it — is that it demonstrates Porcaro's central gift in concentrated form. The groove is technically demanding: a half-time shuffle with ghost notes filling the triplets, a four-on-the-floor pattern in the pre-chorus, melodic bass drum lines in the chorus. Every section requires a different skill set, and the transitions between them have to feel inevitable. Engineer Al Schmitt, who recorded the track, captured a kit sound that let every element of the performance breathe. And Porcaro, who was always candid about his influences, named Bernard Purdie's "Home at Last" groove from Steely Dan's Aja as a direct reference point — a lineage that runs straight back through the records he'd already made. He was building on a tradition he had helped establish.
Porcaro died on August 5, 1992, at thirty-eight. The memorial concert held at the Universal Amphitheater in Los Angeles on December 14 of that year drew George Harrison, Donald Fagen, Don Henley, Michael McDonald, Boz Scaggs, David Crosby, and Eddie Van Halen. The range of those names tells the story better than any discography. These were not people paying respects to a sideman; they were musicians who understood that their best records had a specific feel, and that the feel had a specific source. He was posthumously inducted into the Modern Drummer Hall of Fame in 1993. The grooves, of course, were already in the Hall of Fame. They'd been on the radio for years.
