Jeffrey Steven "Jeff" Pilson (born January 19, 1959, Lake Forest, Illinois) is an American multi-instrumentalist best known for his stint in the heavy metal band Dokken. He was also a member of Dio for much of the 1990s and has been the bassist for Foreigner since 2004.
After the initial breakup of Dokken, Pilson formed his own group called Flesh & Blood in 1989, taking over lead vocal and rhythm guitar duties. After changing the name to War & Peace, Pilson released a total of four albums, starting with 1993's Time Capsule, utilizing different players and line-ups. Pilson went on to collaborate with War & Peace bassist Tommy Henriksen under the name Underground Moon choosing the pseudonym Dominic Moon for himself; the project's sole album was released in 2001 in Europe and Japan.
Pilson reunited with his ex-Dokken bandmate, guitarist George Lynch, in a two-member group called Lynch/Pilson, releasing the album Wicked Underground in 2003. He has also worked as a session bassist with the band Wild Horses (not to be confused with the British band of the same name), guitarist Michael Lee Firkins, and MSG, among others.
In 2010, Pilson participated in a tribute album titled Mister Bolin's Late Night Revival, a compilation of 17 previously unreleased tracks written by guitarist Tommy Bolin prior to his death in 1976. A percentage of the proceeds from this project will benefit the Jackson Recovery Centers.
Although he is known primarily for his work as a bass guitarist, Pilson also plays guitar, cello, and keyboards.
He is also a member of T & N, which consists of the classic Dokken lineup, minus Don Dokken.
In addition to producing his own projects starting with War & Peace, Pilson has also worked in that capacity with several other acts, helming Benedictum's Uncreation (2006) and Seasons of Tragedy (2008), respectively, and Adler's Back from the Dead (2012). He produced Foreigner's 2006 CD, Live in '05, as well as tracks off of their No End in Sight CD in 2008. In December 2012 it was revealed that Pilson would produce the sophomore album by Kill Devil Hill, featuring Pilson's former Flesh & Blood and Dio band mate Vinny Appice on drums.
Pilson has also worked as an actor, having appeared in the movie Rock Star, 2001. Pilson played bassist Jorgen, of the fictional band Steel Dragon, along with Zakk Wylde, future Foreigner band mate, Jason Bonham, who also contributed to the Soundtrack, with Miljenko Matijevic and Jeff Scott Soto as vocalists, who can not be seen. Wylde later stated in an interview for Metal Hammer that before their collaboration he "had only known him as a member of Dokken. I didn't know about all his skills. This guy is unbelievable."
He also contributed to the Mortal Kombat reboot, performing the voice acting for Johnny Cage.
