Steve "Luke" Lukather (born October 21, 1957) is an American Grammy Award-winning guitarist, singer, songwriter, arranger, and record producer best known for his work with the rock band Toto. Lukather has also released several solo albums and, as a studio session guitarist, has arranged, composed, and recorded on over 1000 albums. While his work with Toto is predominantly based on pop rock music, Lukather's solo work spans many genres including rock, prog, jazz and funk.
Notable session keyboardist David Paich and session drummer Jeff Porcaro were high school friends with Lukather. They asked Lukather to join in forming their band, Toto, in 1976 when Lukather was nineteen years old. He was a member of Toto from that time until the band's disbandment in 2008. Lukather's guitar talent and his association with Paich and Porcaro, already established session musicians, allowed him to secure a great deal of session work in the 1970s and 1980s. He is a prolific songwriter, writing or co-writing many songs for Toto and other artists. His career to present has encompassed hundreds of performances and album appearances with Toto and other famous musicians. Lukather has been nominated for 12 Grammy awards, and has won five times.
