Ben Chasny, the principle creative force behind Six Organs of Admittance, loves to release rare singles and recordings that send his fans scurrying through dusty record racks. Fortunately RTZ, which is released as a double CD set and a triple vinyl package, gathers many of these scarce early singles, subscription CDs and oddball recordings. To show you how rare some of this stuff is, the Nightly Trembling record, which is included here, was originally released in an edition of just 33 copies. But recordings of live shows, demos and unreleased material make this a desirable package for even the most hardened of Six Organs aficionados.
