"Rehab Reunion" is the sixth album (fourth studio album) by Hornsby with his touring band the Noisemakers. Released on June 17, 2016, the album is notable in that Hornsby, widely recognized for his piano capabilities, does not play piano on the album, only the dulcimer. The album also marks Hornsby's first release on 429 Records. Like on many of his previous releases, "Rehab Reunion" features collaborations with guest artists. Justin Vernon of Bon Iver sings background vocals on "Over the Rise". Mavis Staples duets with Hornsby on "Celestial Railroad". Also noteworthy is a folk version of "The Valley Road", originally a hit in 1988 with Hornsby's first backing band, the Range.
