Popol Vuh sound best on house-sized speakers overlooking the cruel and infinite ocean, but CDs will do. They made electro-acoustic music for solemn occasions — New Age without deodorant. Distilling 20-plus albums to a single disc this continuous is as questionable as coupling it with remixes, but such is our debased sphere. Unsurprisingly, the best of those remixes — Mouse on Mars’ in particular — work by cramming and collaging instead of trying to maintain the expanse.
