Toto is an American rock band formed in 1977 in Van Nuys in Greater Los Angeles, California. The band's current lineup consists of Joseph Williams (lead vocals), David Paich (keyboards, vocals), Steve Porcaro (keyboards), Steve Lukather (guitars, vocals), David Hungate (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. David Paich and Jeff Porcaro had played together as session musicians on several albums and decided to form a band. David Hungate, Steve Lukather, Steve Porcaro and Bobby Kimball were recruited before their 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. They are best known for the Top 5 hits "Hold the Line", "Rosanna", and "Africa". Several changes to the lineup have been made over the years. 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. The band has released a total of 17 albums, and have sold over 35 million albums to date. The group was honored with several Grammy Awards and was inducted into the Musicians Hall of Fame and Museum in 2009.
