- The Pioneer Brass: "Acres of Clams" (1992, Centaur CRC2131). One track (The Camptown Races, by Stephen Foster) of this predominantly brass ensemble CD features the reed contrabass, played by Philip Neuman.
- The Pioneer Brass "A Pioneer Brass Christmas" (1994, Gagliano Recordings GR505-CD). This CD has one track ("Let It Snow") that features the reed contrabass, played by Philip Neuman, and another track ("Echo (Sonar) Carol") that features the "slide reed subcontrabass" invented and played by Mr. Neuman. Here is what the liner notes say about the slide subcontra: "This arrangement features the slide reed subcontrabass, invented and played by Philip Neuman. It is best described as a slide rackett, made of brass, with a trumpet-like bell and a wide, flat double reed. Its highest note is a semitone below the lowest note available on the common string bass." It is truly deep. The rest of the CD is just excellent brass playing.
