Micro genres are a fickle thing. Night Bus, Witch House and Chillwave all had their short fashionable time but finished when their options got fully exhausted. Some bands seem to outlive this though. Washed Out starting as a bedroom project by Ernest Greene is now a full band releasing their second album Paracosm in August.
All I Know is the best track on the album harking back to the brilliance of his second ep Life Of Leisure but with all the development of being in a band. Chillwave still lives on.
