Tracked in the decade after Duster went on hiatus, Canaan Amber’s debut solo EP CA demonstrates the California-born guitarist’s affection for San Francisco jangle and Santa Cruz surf. Crawling at a banana slug’s pace, Canaan wraps the loneliest one-string guitar solos around a cluster of hollow rhythms and ghostly mumbles. The original 2012 five-song CD has been expanded to include seven other demos plundered from the prolific songwriter’s vault. More Wolf Moon than Black Moon, CA continues to explore and map the hidden galaxies that make up the Duster universe.
