''Nothing ever really disappears,'' Cassandra Jenkins says. ''It just changes shape.'' Over the past few years, she's seen relationships altered, travelled three continents, wandered through museums and parks, and recorded free-associative guided tours of her New York haunts. Her observations capture the humanity and nature around her, as well as thought patterns, memories, and attempts to be present while dealing with pain and loss. With a singular voice, Jenkins siphons these ideas into the ambient folk of her new album. An Overview on Phenomenal Nature honors flux, detail, and moments of intimacy. Jenkins arrived at engineer Josh Kaufman's studio with ideas rather than full songs nevertheless, they finished the album in a week. Jenkins' voice floats amid sensuous chamber pop arrangements and raw-edged drums, ferrying us through impressionistic portraits of friends and strangers. Her lyrics unfold magical worlds, introducing you to a cast of characters like a local fisherman, a psychic at a birthday party, and driving instructor of a spiritual bent.
