It appears that following a trio of December shows, stoner metal legends Sleep will be going on an indefinite hiatus. The band has issued "transmission" which states that a "hypersleep" of "indef. duration" will commence on January 1. You can have a look below.
Prior to going dormant again, Sleep will perform three gigs at Thalia Hall in Chicago on December 29, 30, and 31.
