The Cosmic Rabbit Holes sounds like a lazy prog-rock band. They have all the pomp in their sound of Procol Harum getting ready to jam with an orchestra.
But, they’re laid back dudes who can’t be bothered to think of a theme for their concept album.
Frankly, this all sounds very good, with a meditative vibe that may well get you to return to this tune at least a few times over.
