For that not-so-insubstantial subset of rock fans who savor guitar sounds, the Australian sextet Ocean Alley is a (relatively) new outfit you have to hear. Three of the musicians are guitarists, and the way lead singer Baden Donegal, Mitch Galbraith, and lead guitarist Angus Goodwin weave their guitar lines together, along with keyboardist Lach Galbraith, really give the band a lush and intoxicating sound that lends their psychedelic surf rock its own unique identity.
