UK rave scene dance veterans Orbital broke up in 2014 but have a new album called Optical Delusion on the way. Today they have a new single out, a collaboration with Penelope Isles, the young indie rock band led by siblings Lily and Jack Wolter. Both acts are based out of Brighton, where they met because Penelope Isles’ studio space is upstairs from Orbital’s. They’ve teamed up on a song called “Are You Alive?”
