Steve "Luke" Lukather (born October 21, 1957, San Fernando Valley, California) is an American guitarist, singer, songwriter, arranger, and record producer best known for his work with the rock band Toto. Lukather has played with many artists, released several solo albums, and worked as a composer, arranger, and session guitarist on more than 1,500 albums. He was also a member of jazz fusion band Los Lobotomys, a collaboration of notable session musicians. While his work with Toto was predominantly based on pop rock music, Lukather's solo and side-project work spans many genres including rock, progressive rock, jazz and funk. Session keyboardist David Paich and session drummer Jeff Porcaro were high school friends with Lukather. Lukather was invited 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 split up in 2008. Lukather's reputation as a guitarist and his association with Paich and Porcaro, who were also established artists, allowed him to secure a solid flow 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 has encompassed hundreds of performances and album appearances with Toto and other well-known musicians. Lukather has been nominated for twelve Grammy awards, and has won five times.
