For a band that's been around for more than 10 years, Ghost to Falco is still ridiculously tricky to classify. The music pushes the boundaries of comfort and rewards the audience with unique and intentional songs. One thing is consistent: The man behind the curtain, Eric Crespo, has unfailingly experimented on each of his albums, sometimes as a solo act, and sometimes collaborating on record with more than 30 other musicians, as on 2010's excellent Exotic Believers. Crespo makes cerebral music that ranges from minimal noise tracks that don't have a recognizable structure, to Neil Young-esque, electric-guitar rock 'n' roll songs, to delicate folk tunes punctuated with harmonica. Exotic Believers, is an excellent example of Crespo's talent, which has bounced from Portland to North Carolina but has lately been back in our corner, making music that is insightful, diverse, and surprising.
