Q:I have a test where I am given the following article, what is an answer for the question: What is the last name of the person who held a long-time collaboration with a jazz guitarist? ?  Steven Lee Lukather (born October 21, 1957) is an American guitarist, singer, songwriter, arranger and record producer, best known as a founding member of 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 was a prominent contributor to several studio albums by Michael Jackson, including Thriller, the best-selling album of all time.

While his work with Toto was predominantly based on pop rock music and his solo work ventures into progressive rock and hard rock, many of Lukather's side-projects are focused on jazz fusion. He held a long-time collaboration with jazz guitarist Larry Carlton that produced a Grammy-winning live album, and he was a member of the jazz fusion band Los Lobotomys, a collaboration of notable session musicians. Since 2012, Lukather has toured with former Beatles drummer Ringo Starr's live supergroup, the All-Starr Band. Influenced by such blues-rock guitarists as Jimi Hendrix and Jimmy Page, and such jazz fusion players as Al Di Meola and Frank Gambale, Lukather is known for a "melodic and intense" playing style.
