For every sibling band forged in rivalry, many others mount an unassailable genetic argument for keeping the music in the family. The latter is assuredly the case with Penelope Isles, a brother-sister-centered alt-rock quartet from Brighton (via Isle of Man/Devon) whose debut album, Until The Tide Creeps In, is out now. Formed around the chemistry between dual songwriters Jack and Lily Wolter, the quartet’s expansive DIY mix of translucent dream-pop, fuzz-rock guitars and indie-psych flushes comes lovingly dipped in exquisite harmonies and lustrous melodies - a combination so intuitive you’d think it was in their blood.
