Jeff Chimenti (born October 21, 1968) is an American keyboardist, best known for his ongoing work with former members of the Grateful Dead. Since May 1997 he has played with Bob Weir & RatDog, and has also played on every tour of The Dead (including the Fare Thee Well lineup) and Furthur. He currently plays with Dead & Company.
Early life and music career
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. Once he graduated from high school, he began playing in bands around the Bay area. He played in local jazz bands as well as Les Claypool's Frog Brigade. He has also played back-up for pop acts such as En Vogue.
He was playing in Dave Ellis's jazz quartet when Ellis was hired to play saxophone in Bob Weir & RatDog. Ellis informed him that RatDog was also looking for a new keyboardist. Chimenti was hired and played his first show 28 May 1997. Chimenti has been a member of RatDog ever since and has occasionally performed with Phil Lesh and Friends. While performing, he commonly uses Brent Mydland's Hammond B3 organ.
He performed with The Other Ones during the band's final tour with that name in 2002. 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.
He continued to perform with every version of the Dead that toured in 2003, 2004 and 2009. Following The Dead's final tour in 2009 he joined Bob Weir and Phil Lesh in their project Furthur. Furthur toured consistently between 2009 and 2014.
Chimenti performed at the five 50th anniversary performances of the Grateful Dead in Santa Clara, at Levi's Stadium, on June 27 and 28 2015 and in Chicago, at Soldier Field, on July 3, 4 and 5 2015.
Following the success of the Fare Thee Well shows, he continues to tour with the band Dead & Company, along with former Grateful Dead members Bob Weir, Bill Kreutzmann, and Mickey Hart, as well as John Mayer and former Allman Brothers bassist Oteil Burbridge.
Chimenti has played with one or more former Grateful Dead members for over 25 years (he joined Ratdog in May 1997), which by comparison is as long as the tenure of the last three Grateful Dead keyboardists combined (Keith Godchaux, Brent Mydland and Vince Welnick, 1971-1995).
Outside of music
In 2017 Chimenti served as Music Supervisor on "Red Roses, Green Gold" an Off-Broadway musical featuring the music of Robert Hunter and Jerry Garcia, with additional music by Phil Lesh, Bob Weir and Mickey Hart, and Hunter’s longtime collaborator, Greg Anton. 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.
