Dixon is a jaggedly lyrical trumpeter -- his delivery is as vocalic as that of any free jazz trumpeter except perhaps Lester Bowie.
Dixon's work features open space, wide intervals that do not imply a specific key or mode, and dark backdrops owing to the use of two or more double bassists.
The band recorded the self-titled Archie Shepp-Bill Dixon Quartet LP for Savoy in 1962 (Dixon was briefly the artistic director in charge of jazz for the label).
