Blues-rock keyboard player Barry Goldberg has died aged 83.

He famously played with Bob Dylan throughout the 1960's, including the 1965 Newport Folk Festival where Bob Dylan performed with an electric guitar for the first time, portrayed recently in A Complete Unknown.

According to a representative, Bob Merlis, Goldberg died in hospice care after a 10-year struggle with non-Hodgkin lymphoma on Wednesday. His wife of 53 years Gail Goldberg and son Aram were at his bedside.

Goldberg was born in Chicago on Christmas Day 1941. He was the grandson of U.S. Supreme Court justice Arthur Goldberg and the son of Frank Goldberg and Nettie Goldberg, the latter of whom played barrelhouse piano and was part of a Jewish theatre circuit.

He formed The Electric Flag with Mike Bloomfield, Buddy Miles and Harvey Brooks back in 1967. The group provided the soundtrack for the Peter Fonda  film The Trip as well as releasing the album A Long Time Comin' in 1968.

His self-titled Barry Goldberg album, released in 1974, was the only album Dylan ever produced for another artist.

As well as playing with Dylan, Goldberg’s long music history includes writing and producing for artists such as The Butterfield Blues Band, Steve Miller, the Ramones, Leonard Cohen, the Flying Burrito Brothers, Mitch Ryder, Stephen Stills, Rod Stewart, Bobby Blue Bland, Percy Sledge and Kenny Wayne Shepherd.

In later years he was part of the blues-rock group The Rides with Stephen Stills and Kenny Wayne Shepherd. They achieved two No. 1 blues albums in the mid-2010s, Can't Get Enough and Pierced Arrow.

In place of flowers, the family suggests that donations be made in his name to the Bear League via savebears.org.
