With a surname like Guthrie comes some expectations, and even though this Guthrie (no actual relation) isn't singing about America's politicians and workers, he has an empowering songbook. Like any great songbook, there's a lot of variety in the song material and the way Guthrie presents it. This folk singer with a big voice fills the whole room with deep-end guitar and climbing vocals. In the next song, Guthrie can whisper and roll out love lyrics like Leonard Cohen. The North Carolina native can sling a banjo and buzz on a harmonica, but his guitar-playing, a fun and bright strumming pattern, is complex enough on its own. With Stephen Warwick & Secondhand Stories, John Common & Blinding Flashes of Light, and Sarah Bowman. $8. Snug Harbor. www.snugrock.com.
