Query: Musical terra incognita

This five-song symphonic cycle is by turns eerie, dissonant, hauntingly beautiful, and jaw-droppingly strange. This is music that inhabits some previously unexplored hinterland between pop dementia and avant garde classicism. Probably the best of the Residents' early records and my personal favorite. One of the most singular and eccentric records ever made.
