New Englanders Shanti Curran and Buck Curran have first names as unique and free-spirited as the music they make. The married couple’s take on various folk styles — ambient, bluesy, British — is druggy in the holistic sense, more “Lord of the Rings” than Mumford & Sons (“British” here refers to the classic folk breakthroughs of Pentangle, The Incredible String Band, Fairport Convention, and so on). The natives of the other Portland, in Maine, came through here last year and are always worth seeing, but especially this time with opening act Mariee Sioux, whose collaborative EP with Bonnie “Prince” Billy, Bonnie & Mariee, was released this spring on Spiritual Pajamas Records. —Peter Berkowitz
