It’s a cool endeavor to break a cohesive unit into its parts, and then explore the nuances that make the whole unique. If Jazzanova is the six-member unit, then Roskow Kretschmann is one of those important parts. New Aspects, his first solo album in over seven years, finds Kretschmann (as Kosma) embracing a predominantly mellow downtempo niche that’s both spiritual and uplifting. By no means is this mere background music-New Aspects repeatedly drives down the road less traveled, and makes the trip enjoyable.
