Toto was an American rock band formed in 1977 in Los Angeles. The band's most recent lineup consisted of Joseph Williams (lead vocals), David Paich (keyboards, vocals), Steve Porcaro (keyboards), Steve Lukather (guitars, vocals), plus touring members Lenny Castro (percussion), Warren Ham (saxophone), Shem von Schroeck (bass) and Shannon Forrest (drums). Toto is known for a musical style that combines elements of pop, rock, soul, funk, progressive rock, hard rock, R&B, blues, and jazz.
Paich and Jeff Porcaro had played together as session musicians on several albums and decided to form a band. David Hungate, Lukather, Steve Porcaro, and Bobby Kimball were recruited before the first album release. The band enjoyed great commercial success in the late 1970s and 1980s, beginning with the band's eponymous debut released in 1978. With the release of the critically acclaimed and commercially successful Toto IV (1982), Toto became one of the best-selling music groups of their era.
Widely known for the Top 5 hits "Hold the Line", "Rosanna", and "Africa", the makeup of the group continued to evolve. Hungate left in 1982; Kimball left in 1984, but rejoined the band in 1998, leaving again in 2008. Jeff Porcaro died in 1992 of a heart attack. Hungate rejoined Toto as a touring musician and later a band member. In 2008, Lukather announced his departure from the band, and the remaining band members later went their separate ways. In the summer of 2010, Toto reformed and went on a short European tour, with a new lineup, to benefit Mike Porcaro, who had been diagnosed with amyotrophic lateral sclerosis (ALS) and was no longer an active member of the band. He died in 2015. The band celebrated its 40th anniversary in 2017. Toto announced an extended hiatus following the final leg of their 40th anniversary tour in 2019.
Toto has released 14 studio albums, and has sold over 40 million records worldwide. The group has been honored with several Grammy Awards and was inducted into the Musicians Hall of Fame and Museum in 2009.
