In a way, Chelsea Wolfe is on a journey to the surface of her own music. 2012 finds releasing her first acoustic emanation, titled ''Unknown Rooms: A Collection of Acoustic Songs''. The experience is a secret shared, a side of our heroine rarely seen or heard, and the making was as intimate as it gets: recorded in the woods of Northern California and at Wolfe's L.A. home, co-produced by her bandmate Ben Chisholm, with players Ezra Buchla (viola), Andrea Calderon (violin) and Daniel Denton (bass).
