Concurrently with the bluegrass project, Hornsby recorded a jazz album, "Camp Meeting". with Christian McBride (bass) and Jack DeJohnette (drums). Alongside original compositions by Hornsby, the trio delivered "newly reharmonized versions" of tunes by John Coltrane, Miles Davis, Thelonious Monk and Bud Powell, a previously unrecorded Ornette Coleman work ("Questions and Answers") and an early Keith Jarrett composition ("Death and the Flower"). The trio made a series of appearances in the summer of 2007, including the Playboy Jazz Festival, the Newport Jazz Festival and at the Hollywood Bowl.
