Played bass for Captain Beefheart & the Magic Band in the 1960s and 1970s.

In 1963, after moving to Lancaster, California, he joined up with future member of the Magic Band, Bill Harkleroad (aka Zoot Horn Rollo) in a band named B.C. & The Cavemen. Later, while performing in the Magic Band, he played on such critically acclaimed albums as The Spotlight Kid and Trout Mask Replica. Tensions between Captain Beefheart and members of the band led to a split in 1974, when Boston left to form Mallard with bandmates John French, Harkleroad, John Thomas and Art Tripp. Following the demise of Mallard, he continued performing in various bands as guitar player and bassist. Always interested in studio performance, he remained active in his own recording studio. Between 2003 and 2006, members of the Magic Band regrouped and performed on a world tour. He has also released a solo album Love Space.
