JP & the Chatfield Boys/Run Boy Run/The Luckey Ones

Rooted in one of the most traditional genres of American music, Run Boy Run, who share tonight’s bill with JP & the Chatfield Boys and the Luckey Ones, manages to bring a fresh flavor to good ol’ bluegrass music. Female vocals coupled with violin and mandolin combine to create an almost trancelike atmosphere of nostalgia that’s both beautiful and made of pure Americana. The group of five formed in 2009 and last year’s So Sang the Whippoorwill garnered national acclaim, even catching the ear of Prairie Home Companion host Garrison Keillor. Gems such as “So Sang the Whippoorwill” (same title as their album) and “Little Girl” suggest the band’s interest in music from another time. The singing is very understated and doesn’t take the spotlight off the lovely music. 9 p.m., $10. Beachland Tavern.
