Featuring cello and acoustic guitar, the folk group Tall Heights features the kind of pitch-y vocals that characterize the music of Ani DiFranco. Darlingside features four singers whose “tightly-arranged tunes draw from the unexpected, including strains of bluegrass, classical, and even barbershop.” The two groups share the stage tonight at the Happy Days Lodge in Peninsula. The Conservancy Canteen will be serving up the grub: fresh, locally-sourced cuisine like Cuban sandwiches, antipasto skewers and spiced beer nuts. Tickets are $17 for non-members, $12 for Conservancy members. (Niesel)
