From early training in Classical music to studying jazz improvisation/theory as a vocalist to poignant philosophizing with Grammy-winning artists, the whole mix has helped David to communicate songs in ways that speak to the human heart. His sound has been compared to Chet Baker and Mel Torme, but David's sound is "a unique voice with pathos, depth and control" (Ann MacDonald).
David studied and/or played with Ray Brown (flugelhornist), Dave Holland, Bobby McFerrin, George Russell, Don Thompson, Kenny Wheeler and Mark Levine. He recorded with Grammy-nominated arranger Phil Mattson, singing the title track of Mr. Mattson's album Here's to Life. Influences include Lambert, Hendricks and Ross, Shirley Horn, Miles Davis and John Coltrane.
