With the air of an ancient bard, Robin Williamson interweaves visionary poetry and narrative with a variety of Anglo and Celtic musical strains on Trusting in the Rising Light. The Scottish singer/songwriter’s oracular vocals and haunting harp, fiddle, and guitar work—augmented by Mat Maneri’s dissonant viola and Ches Smith’s evocative percussion—takes his latest work beyond the confines of traditional folk into blues and avant-garde realms. Mystically tinged compositions like “Our Evening Walk," “Just West of Monmouth,” and “The Islands of the Inner Firth” are worthy additions to Williamson’s idiosyncratic, ever-fascinating catalog.
