Toto was formed in Los Angeles in 1978 by David Paich (b. June 21, 1954, Los Angeles; keyboards, vocals), Steve Lukather (b. October 21, 1957, Los Angeles; guitar, vocals), Bobby Kimball (b. Robert Troy Kimball, March 29, 1947, Vinton, LA; vocals), Steve Porcaro (b. September 2, 1957, Connecticut; keyboards), David Hungate (b. Texas; bass), and Jeff Porcaro (b. April 1, 1954, Hartford, CT; d. August 5, 1992, Hidden Hills, CA; drums). Paich was the son of arranger Marty Paich; the Porcaros were the sons of percussionist Joe Porcaro. The bandmembers had met in high school and at studio sessions in the 1970s, when they became some of the busiest session musicians in the music business. Paich, Hungate, and Jeff Porcaro wrote songs for and performed on Silk Degrees, the multi-million-selling 1976 album that combined pop, rock, and disco elements into a slick combination which heavily influenced mainstream pop music.
Toto released its self-titled debut album in October 1978, and it hit the Top Ten, sold two-million copies, and spawned the gold Top Ten single "Hold the Line." The gold-selling Hydra (October 1979) and Turn Back (January 1981) were less successful, but Toto IV (April 1982) was a multi-platinum Top Ten hit, featuring the number-one hit "Africa" and the Top Tens "Rosanna" (about Lukather's girlfriend, movie star Rosanna Arquette) and "I Won't Hold You Back." At the 1982 Grammys, "Rosanna" won awards for Record of the Year, Best Pop Vocal Performance, and Best Instrumental Arrangement With Vocal; and Toto IV won awards for Album of the Year, Best Engineered Recording, and Best Producer (the group). In 1984, a third Porcaro brother, Mike (b. May 29, 1955), joined the group on bass, replacing Hungate. Then lead singer Kimball quit and was replaced by Dennis "Fergie" Frederiksen (b. May 15, 1951, Wyoming, MI).
Toto's fifth album, Isolation (November 1984), went gold, but was a commercial disappointment. Frederiksen was replaced by Joseph Williams (b. Santa Monica), the son of the conductor/composer John Williams, for Fahrenheit (August 1986). Steve Porcaro quit in 1988, prior to the release of The Seventh One. In 1990, Jean-Michel Byron replaced Williams for the new recordings on Past to Present 1977-1990, then left, as Lukather became the group's lead singer. Jeff Porcaro died of a heart attack in 1992, but was featured on the group's next album, Kingdom of Desire. By this time, Toto was far more popular in Japan and Europe than at home. The group added British drummer Simon Phillips. Tambu, released in Europe in the late fall of 1995, appeared in the U.S. in June 1996. For 1999's Mindfields, Bobby Kimball returned to the lineup after a 15-year absence. The group members continued to do session work during the band's tenure, contributing significantly to the sound of mainstream pop/rock in the 1970s, '80s, and '90s. ~ William Ruhlmann, Rovi
