Now best known as a film music composer, Delia began his career in the late 1960s playing piano and singing with The Bruthers, a group that mainly served as a backing band on concert tours with artists like Stevie Wonder and Isley Brothers. During the 1970s he was active as a jingle composer, session keyboardist and arranger, but he also began composing movie scores.

Since then, he has worked extensively with director Abel Ferrara, supplying the music for Ms. 45, Driller Killer, Bad Lieutenant, The Addiction and others. He also composed the music for Ferrara's The Blackout which spawned a collaboration with another Ferrara favourite, Schoolly D, that was released as a single (The Player).

Since the 1980s, Delia has also often collaborated with David Johansen (also known as Buster Poindexter).
