Wanted this on vinyl as soon as I heard it. Grand and wild. Each side is like its own Koyaanisqatsi-esque End Credits for the 1970s; while Exploration is a explosive, expressive, anthemic and loud, Discovery is the cool side, with more muted tones and contemplative phrases until it ramps up to a grand finish echoing the beginning of the record. Excellent, abstract, experimental stuff. jammingdevice
