American bassist, most known for his work in Blood, Sweat And Tears. His early career began in "The Bohemians" with Tim Buckley, with whom he played on Buckley's solo album.
Fielder worked for a period in "Mastin & Brewer" (Later to become Brewer And Shipley), before working in Zappa's "MOI" band on rhythm guitar alongside bassist Roy Estrada for the "Absolutely Free" album. "Mastin & Brewer" ex manager, Frazier Mohawk, then managed Buffalo Springfield so, when bassist Bruce Palmer left due to passport problems, Fielder was called in by Mowhawk. (Another Zappa connection is Mohawk, aka Barry Friedman, married ex Zappa musician Sandy Hurwitz - aka Essra Mohawk - aka 'Uncle Meat')
Palmer later returned to the band and Fielder then became a member of Blood, Sweat & Tears, thanks to an earlier friendship struck with Al Kooper during the latter's time in The Blues Project. Fielder played on six of the band's albums and cites their appearance at Woodstock as one of the highlights of his career. In 1977 he joined the line-up of Neil Sedaka's band.
