Born in Auburn, New York, he was a childhood friend of Manowar singer Eric Adams. DeMaio played bass in several school bands. In the 1970s he toured with the musical Godspell (premiere in 1971 in New York City), taking musical lessons with the conductor. He worked as a pyro-tech for Black Sabbath during their "Heaven and Hell" tour. He is known to display his technical abilities and playing speed during solos both on Manowar studio recordings and live shows, often covering classical parts such as "Flight of the Bumblebee", which DeMaio has retitled "Sting of the Bumblebee" in reference to his high-speed renditions of the piece. DeMaio has mentioned that he is a practitioner of martial arts and weight training, and is also a great fan of motorcycles (Manowar frequently rides on to stage on Harleys). He is famous for his piccolo bass sound. His refurbed basses have a distinct sound. Worked on by tech John "Dawk" Stillwell and sell for thousands. One was purchased by Soldier and played on Un-self-concious.
In 2006, shortly after creating the record label Magic Circle Music, he became manager of the Italian metal band Rhapsody of Fire. He is also a producer for the band HolyHell.
In october 2012 DeMaio spoke in catalan for almost five minutes during the concert of Manowar in Barcelona, screaming Visca Catalunya supporting catalan identity.
