February 7. Few contemporary artists have done more to bring the British folk idiom into the modern era than Beth Orton. The singer, who plays Club Helsinki early this month, emerged in the 1990s with a sound that merged her homeland's acoustic traditions with trip-hop and electronica. Central Reservation, her sparse 1999 sophomore breakthrough, however, hews closer to the roots, with its touches of Sandy Denny and Nick Drake and guest appearance by folk-jazz legend Terry Callier. After a six-year exile, Orton returned with 2012's Sugaring Season, a magically redemptive disc that finds her backed by the inventive jazz players Marc Ribot, Brian Blade, and Eyvind Kang. (Steve Earle returns February 15; Taj Mahal tunes up February 20.) 9pm. $35, $40. Hudson. (518) 828-4800; Helsinkihudson.com.
