Sleep - The Sciences - 2xLP

The Sciences is the fourth studio album by American doom metal band Sleep. The album was released with little warning on April 20, 2018 through Third Man Records. It was the band's first full-length album since Dopesmoker (2003) on which the song "Sonic Titan" appeared as a live bonus track.

Just a month after the release of The Sciences, Sleep released the non-album song "Leagues Beneath" through Adult Swim's 2018 weekly single series.
