9 Horses is a chamber jazz group from the United States consisting of composer and mandolinist Joseph Brent, violinist Sara Caswell, and bassist Andrew Ryan, originating from New York City.

However, when Brent's commitments to Regina Spektor's touring band and his teaching responsibilities at Mannes College spread his time too thin, he put the quartet project on hold.

[5] The recording includes percussionist Ben Wittman, but live performances generally feature either the trio alone, or guest musicians such as Emily Hope Price or Ike Sturm.

[20] Strings Magazine called it, "A restless shapeshifting amalgam of jazz, rock, pop, improvisation, melody, and variegated acoustic and electronic textures… Only 9 Horses can make such a complex and experimental mix of timbres, colors, and themes sound so effortless and free,"[21] and Textura added, "Rather than get sidetracked by futile attempts at categorizing, one's best advised to go where the music leads and simply enjoy a seventy-seven-minute ride that's ever scenic and always stimulating… If (Caswell) hadn't already distinguished herself in so many ways before it, her playing on Omegah would qualify as a star-making turn.

Albums by artists such as Sam Sadigursky,[25] Joe K. Walsh,[26] Matt Aronoff,[27] and Jacob Jolliff[28] followed, and Adhyâropa continues to release a cross-genre selection of jazz, Americana, Classical, and World music.
