Keith Richard Godchaux (July 19, 1948 – July 23, 1980) was a pianist best known for his tenure in the rock group the Grateful Dead from 1971 to 1979.

Godchaux was born in Seattle, Washington, and grew up in Concord, California, a regional suburban center within the East Bay of the San Francisco Bay Area. He began piano lessons at age five at the instigation of his father (a semi-professional musician) and subsequently played Dixieland and cocktail jazz in professional ensembles as a teenager. According to Godchaux, “I spent two years wearing dinner jackets and playing acoustic piano in country club bands and Dixieland groups…I also did piano bar gigs and put trios together to back singers in various places around the Bay Area…[playing] cocktail standards like ‘Misty’ the way jazz musicians resentfully play a song that’s popular – that frustrated space… I just wasn’t into it… I was looking for something real to get involved with – which wouldn’t necessarily be music”. He met and married former FAME Studios session vocalist Donna Jean Thatcher in November 1970; their son Zion, of the band BoomBox, was born in 1974.

The couple introduced themselves to Jerry Garcia at a concert in August 1971; coincidentally, ailing keyboardist/vocalist Ron “Pigpen” McKernan (who would go on to play alongside Godchaux from December 1971 to June 1972) was unable to handle the rigors of the band’s next tour. At the time, Godchaux was largely supported by his wife and irregularly employed as a lounge pianist in Walnut Creek, California. While he was largely uninterested in the popular music of the era and eschewed au courant jazz rock in favor of modal jazz, bebop, and swing, several sources^[who?] claim that he collaborated with such rock acts as Dave Mason and James and the Good Brothers, a Canadian trio acquainted with the Grateful Dead.
