GOLDEN OAK Sunday, Sept. 9 2 p.m. An emerging sound in New England folk music, this Portland-based, indie-soul-folk sibling duo, Zak (guitarist) and Lena Kendall (vocalist) started making music together as kids and the bond of brother and sister is evident in their carefully crafted songs, poetic lyrics, and flowing harmonies. Rounding out the band are Mike Knowles - electric/upright bass and drummer Jackson Cromwell.
