Here’s an archival gem for Elephant 6 heads: a collaborative EP from the late visionary Will Cullen Hart and Elf Power’s Andrew Rieger. Though very brisk, the timing of this snapshot (culled from recording sessions circa 1999-2000) vividly conjures the opaque psychedelic sweet spot of the Olivia Tremor Control and beginnings of Hart’s essential offshoot project Circulatory System.
