Got tickets to Mike Gordon’s Revolution Hall show on Friday? Get there (425 River St., Troy) in time for opener Danny Barnes. The leader of Austin’s semi-legendary roots rockers the Bad Livers, Barnes touches down everywhere in the Americana spectrum on his quite amazing album “Pizza Box.”

He spent three years writing the songs on this astounding album, full of wit and fun and fire, playing everything with strings himself — including lots of banjo — and getting help from big fan Dave Matthews.
