Question: Who has worked with more artists, Taylor Momsen or Steve Lukather?
Context: Transition is the seventh studio album by Steve Lukather, released on vinyl and as a jewel case CD on January 21, 2013 by Mascot Records.  In Europe a limited edition Digibook was also released, containing a booklet with studio pictures and liner notes from Lukather and producer C. J. Vanston. Lukather is the first solo album from Toto guitarist Steve Lukather released in 1989. Ever Changing Times is the fifth solo album of Steve Lukather.  It was his first album since leaving Toto.  In March 2008, a site was launched in order to promote the album.  According to Lukather, the album shows a lot of his influences and music he likes. Taylor Michel Momsen (born July 26, 1993) is an American singer, songwriter, former actress, and model.  She is known for being the lead singer and frontwoman of the American rock band The Pretty Reckless.  She is also known for portraying the character of Jenny Humphrey on the CW teen drama series "Gossip Girl" (2007–2012) and Cindy Lou Who in the film "Dr. Seuss' How the Grinch Stole Christmas" (2000). 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. Luke is the third solo album by Steve Lukather released in 1997.  It was a much different and more introspective album than Lukather's previous two solo efforts.  The album is a concentrated collection of many of Lukather's musical influences, and he deliberately let those influences come out on the album.  "Luke" is an experimental album, and like "Candyman" it was recorded mostly in live sessions with minimal overdubbing and processing afterward.  "Luke" also features instrumentation not heard on previous Lukather albums such as pedal steel, harmonicas, Mellotrons, and experimental guitar, bass, and drum sounds. Candyman is the second solo album from Steve Lukather.  It was a collaboration of musicians who were for the most part also in Lukather's band Los Lobotomys.  Toto familiars Simon Phillips and David Paich participated as well as David Garfield, John Pêna, Chris Trujillo, Lenny Castro, Larry Klimas, Fee Waybill, Richard Page and Paul Rodgers.  Lukather recorded the album in mostly live takes with little overdubbing. Michael Landau (born June 1, 1958) is an American musician, engineer, and record producer.  He is a prolific session musician and guitarist who has played on a large number of albums since the early 1980s with artists as varied as Boz Scaggs, Minoru Niihara, Joni Mitchell, Seal, Michael Jackson, James Taylor, Helen Watson, Richard Marx, Steve Perry, Pink Floyd, Roger Daltrey, Glenn Frey, and Miles Davis.  Landau, along with fellow session guitarists Dean Parks, Steve Lukather, Michael Thompson and Dann Huff, played on many of the major label releases recorded in Los Angeles from the 1980s–1990s.  He has released music with several record labels including Ulftone Music and Tone Center Records, a member of the California-based Shrapnel Label Group. All's Well That Ends Well is the sixth studio album by Steve Lukather, released on vinyl and as a jewel case CD on October 11, 2010 by Mascot Records.  In Europe a limited edition Digibook was also released, containing a booklet with studio pictures and liner notes from Lukather and producer CJ Vanston, as well as a personal message from Lukather.  The album is dedicated to his late mother Kathy. No Substitutions: Live in Osaka is a live album by Larry Carlton and Steve Lukather, released in 2001 through Favored Nations.  In 2002, the album won Carlton and Lukather, along with engineer/recorder Yoshiyasu Kumada and editor/producer Steve Vai, the Grammy Award for Best Pop Instrumental Album.
