David Martin Frank (born November 13, 1957) is an American music producer, composer, classically trained pianist, and founding member of the 1980s R&B group the System.

Frank had already been experimenting with getting electric guitar sounds out of his Farfisa organ, and was inspired by this encounter to continue pursuing electronic musical directions.

[citation needed] In 1981, while he was working in New York City, Frank was called in to do a session for a local studio owner who suggested that he use the time to create a dance song.

As keyboard synthesist and arranger David helped out on hit recordings that defined the sound of that era with Chaka Khan's "I Feel For You", Phil Collins' "Sussudio,"[3] and Mtume's "Juicy Fruit."

And lastly he was recognized for the System's #1 hit "Don't Disturb This Groove" in which Frank firmly established his prowess as a bass-groove synthesizer innovator and master.

[citation needed] Frank and Murphy produced tracks on albums for artists including Ashford and Simpson, Phillip Bailey of Earth Wind and Fire, Jeff Lorber, Angela Bofill and Nona Hendryx.

He also arranged horns on Michael McDonald's most recent album Wide Open and was credited on "Crying in the Club" by Camila Cabello, which samples "Genie in a Bottle.
