Jeff Chimenti (born October 21, 1968) is an American keyboardist, best known for his ongoing work with former members of the Grateful Dead.

[1][2][3] A native of the San Francisco Bay Area, Chimenti began playing piano when he was four and he studied formally from the age of seven to around the time he finished high school.

This was the first time that Bob Weir, Phil Lesh, Bill Kreutzmann and Mickey Hart all performed together since the disbandment of the Grateful Dead in 1995.

During early 2015 Chimenti joined musicians John Kadlecik, Reed Mathis and Jay Lane in the band the Golden Gate Wingmen.

The production was directed and choreographed by Rachel Klein, featured a book by Michael Norman Mann, and performed at the Minetta Lane Theatre in New York City.
