Years after the release of Volume One in 1991, Sleep’s Holy Mountain in 1992 and Dopesmoker in 2003, Matt Pike hard at work with HIGH ON FIRE and bassist / vocalist Al Cisneros with OM, heavy music needed one of its essential minerals back.

In 2009, falling in on either side of NEUROSIS drummer Jason Roeder, SLEEP, like a wooly mammoth awoken from centuries of frozen slumber, once again walked the earth. You could almost hear the universe sigh in relief that SLEEP was back. 2014 saw SLEEP release a single-sided 12” with a new song, The Clarity, giving fans a glimpse of what would hopefully be more to come. And so, the wait began . . .

All good things take time. In 2018 SLEEP fans were given a reason to break out their finest and get it lit because record stores all over the world were now stocking THE SCIENCES, Sleep's first full-length album of new recordings since 1998. The sonic titans have reaffirmed their place at the top of the riff pyramid.
