Barry Goldberg, an acclaimed keyboard player known for his performance with Bob Dylan at the 1965 Newport Folk Festival, has died at the age of 83. Goldberg was part of a wave of white musicians in Chicago in the 1960s who created their own brand of blues-based rock. He played with various rock luminaries and made his mark as a songwriter, collaborating with artists like Gram Parsons and Gladys Knight & the Pips. Despite his extensive career, Goldberg will always be closely associated with Dylan's groundbreaking electric set at Newport. The impact of that performance has been debated for decades.
