Zao have released "Croatoan" from their forthcoming album, The Crimson Corridor, due out on April 9.

"Based off its origin and without clear definition, the word 'Croatoan' embodies an unsettling feeling of helplessness to me," vocalist Dan Weyandt tells Decibel.

"This song is a vehicle for that feeling and relates it back to dissociation and being lost in strange dimensions and dreams."
