David Thomas Roberts (born January 16, 1955) is an American composer and musician, known primarily as a modern ragtime composer. Roberts is also a painter in a primitivist style.
Born in Moss Point, Mississippi, United States, his first recording, "Music For a Pretty Baby", appeared in 1978. Pieces such as "The Early Life of Larry Hoffer", "Roberto Clemente", "Pinelands Memoir", "Through the Bottomlands", and the suite, "New Orleans Streets" have caused Roberts to be considered one of the leading contemporary ragtime-based composers. The New Orleans historian Al Rose called him "the most important composer of this half of the century in America."
Roberts coined the term "Terra Verde" (meaning "green earth") as a label for compositions which can not be considered as conventional ragtime, mostly by contemporary ragtime writers such as himself, Frank French, Scott Kirby, Hal Isbitz and others.
Roberts also works as a writer and visual artist, and is currently writing a critical history of New Ragtime. His mixed-media art appears in the magazine of visionary art, Raw Vision, and his poetry has been anthologized in Another South, a collection of experimental writing published in 2003 by the University of Alabama Press.
