"A trudging, monolithic record that slowly builds and expands until it consumes you." - Spin

“A cavernous, slow-burning mass of doomy riffs” — Stereogum

“It's a voyage.” — Noisey/Vice

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, the song is a testament to what has made The Sciences such a success: bottomless tone, spacetime-melting riffs, and an unparalleled aural experience from start to finish. “Leagues Beneath," features the full 17-minute hadal plunge on the A-side, with a tentacled aquanaut nightmare etching on the B-side.
