With instruments such as banjos, mandolins, and twangy acoustic guitars it’s surprising that Adios Ghost isn’t more of a new grass band. Instead this Brooklyn quartet goes the rout of experimental indie folk, including varied percussion, hollow harmonies, and echo-like vocals. Some tracks start with a mellow, classic sound before breaking down on a unique beat like "October Snow" or an electric frenzy like "Fernseher." This music is the rebellious teenager of Bluegrass and Folk, throwing away old traditions and embracing the Brooklyn indie scene. Their latest self-titled EP is available here. – Lucy Sherman
