Leagues Beneath is the first release immediately following Sleep's long-prophesied, critically-acclaimed opus The Sciences. Recorded as a part of a series of songs for Adult Swim, this 12" single is a testament to what has made The Sciences such a success: bottomless tone, spacetime-melting riffs and a unparalleled aural experience from start to finish. Leagues Beneath is a full 17 minute plunge, now available to experience on black vinyl. B-side is an etching.
