Hubbard began playing bass at 14, and went on to join local Rhode Island band Roomful of Blues. In 1984, he began working with the Fabulous Thunderbirds, when they signed with Epic Records. They released their first record, Tuff Enuff, with Hubbard in 1986.

He stayed with the group for 10 years.

He also worked with Stevie Ray Vaughan, Bonnie Raitt, Carlos Santana, and Big Joe Turner.

The bassist battled drug and alcohol abuse throughout his life and spent two years in a Texas prison on drug charges. In 2014, he was hospitalised with diabetes.
