Since the 1990s, Duval has been active principally on the New York City jazz scene. He did not begin recording regularly until the 1990s, but since then has appeared on a very large number of albums, particularly on the labels CIMP, Cadence Jazz, and Leo Records. As a result, Duval was described by Allmusic as "unquestionably...one of the most-recorded free jazz bassists on the planet". Todd Jenkins describes Duval and drummer Jay Rosen as the "house rhythm section" for CIMP, given the number of recordings on which they have jointly appeared.:231 Duval's freedom of expression is paramount in his playing. Duval plays his Hutchings bass more often like a violin, guitar or lead saxophone. He displays fast lines and rich textures. Seldom does he play the bass in a traditional role low pitch rhythmic role. Instead he freely interacts with other members within the ensemble.
