Answer by taking a quote from the following article:

Steven Lee Lukather (born October 21, 1957) is an American guitarist, singer, songwriter, arranger and record producer, best known for his work with the rock band Toto. A prolific session musician, Lukather has recorded guitar tracks for more than 1,500 albums representing a broad array of artists and genres. He has also contributed to albums and hit singles as a songwriter, arranger and producer. Lukather has released seven solo albums, the latest of which, Transition, was released in January 2013.

Steven Lee Lukather was born on October 21, 1957, in San Fernando Valley, California. In an interview with online publication "Guitarhoo!" he said: "I had a music teacher in grammar school that made me play the violin. It was 1965. I had been playing guitar for a year (after the Beatles changed our lives), and they had NO use for a guitar player." He then played keyboards and drums, and then taught himself how to play the guitar starting at age seven, when his father bought him a Kay acoustic guitar and a copy of the Beatles album Meet the Beatles. Lukather has said that the album "changed his life" and that he was greatly influenced by the guitar playing of George Harrison in particular.  In high school, Lukather met David Paich and the Porcaro brothers (Jeff, Steve, and Mike), all of whom eventually became members of Toto. Lukather, who had been a self-taught musician, began taking guitar lessons from Jimmy Wyble. With Wyble, Lukather expanded his knowledge of wider aspects of music, including orchestration. It was during this period in the early 1970s that Lukather became interested in the idea of becoming a session musician, a vocation that provided opportunities to play with a variety of famous musicians.  Jeff Porcaro, who had been playing drums with Steely Dan since 1973, became a mentor to Lukather and furthered his interest in session work. Lukather's first job in the music industry was studio work with Boz Scaggs, after which Paich and Jeff Porcaro--who had become prominent session musicians in their own right--asked Lukather to join them in forming Toto in 1976 along with Bobby Kimball, David Hungate, and Steve Porcaro.
