Bluegrass. Newgrass. Rock N' Rollgrass. As John Cowan proves, true innovators defy easy categorization. His ability to move easily between music styles while bending genres into creative new forms has made him one of acoustic music's most significant voices for over three decades. Cowan rose to fame as the lead singer of New Grass Revival, which included renowned band-mates Sam Bush, Bela Fleck and Pat Flynn. The band introduced a new generation of music fans to an explosive, experimental brand of bluegrass. Since NGR, Cowan has followed his creative muse across a diverse landscape of music, delivering a string of acclaimed albums along the way. Now, he returns to his acoustic roots, teaming with an A-list of musicians and noted rock producer Jay Joyce (Patty Griffin, John Hiatt, Tim Finn). The result is the powerful New Tattoo.
