The immensely popular and eclectic roots/pop outfit Lake Street Dive is used to headlining festivals these days, but they may still be most at home in intimate club settings where their jazzy, psychedelic grooves raise the roof and the quirks and soul of Rachael Price’s voice really come across. The Boston band makes a stop at Club Helsinki in Hudson on Labor Day weekend, Saturday, September 5 at 9 p.m. Tickets cost $45 and $35 and are available at www.helsinkihudson.com. Club Helsinki is located at 405 Columbia Street in Hudson.
