Listen to this well-credentialed Nashville quintet, and you’ll hear propulsive rock, gritty blues, heart-searing soul, sinewy grooves, sublime vocal harmonies and a rich, earthy sensibility steeped in Americana roots. What to call it? Drummer and co-founder Steve Gorman favors “a rock band that can jam.” These musicians can certainly do that. Gorman, of course, also co-founded The Black Crowes and is considered one of the best rock drummers of his generation, playing not only with the Crowes, but also with Jimmy Page, and Stereophonics, among others. Singer Joan Osborne has released seven albums since her triple-platinum 1995 debut, Relish, and its Top 5 hit, “One of Us;” she’s also collaborated with The Dead, Phil Lesh & Friends, and Motown’s Funk Brothers. Singer-guitarist-keyboardist Jackie Greene, who performed with The Black Crowes during the band’s 2013 tour, has seven solo albums to his credit and has logged time in Phil Lesh & Friends, among others. Tom Bukovac is a first-call Nashville cat who won five consecutive MusicRow Session Guitarist of the Year awards, while bassist Nick Govrik performed in his former band Highwater and played more recently with singer Mike Farris. Those strengths are on full display throughout their debut album, Trigger Hippy, released by Rounder Records. The tunes seamlessly blend together the Trigger Hippy members’ individual sounds. Trigger Hippy continue to tour the world.
