Toto is an American rock band founded by some of the most popular and experienced session musicians of the era. Toto enjoyed great commercial success in the 1980s and although their popularity in the United States diminished in the 1990s and 2000s, they continued to tour and sold out arenas, clubs, and theaters internationally. As a result of guitarist Steve Lukather's departure from the band, which he agreed with the other members, Toto broke up at the end of their 2008 tour. They are back together since February 2010.
