If their first album in 15+ years isn't enough new Sleep for you, you're in luck. The stoner metal legends have now unleashed nearly 17 more minutes of sludge in the form of the new song "Leagues Beneath." It's for the Adult Swim singles series, and it's actually the second time they contributed to this series; the first was 2014's "The Clarity," which was their first piece of new music since their then-final album Jerusalem/Dopesmoker. Listen to "Leagues Beneath" below.

As mentioned, Sleep are touring, including two Brooklyn Steel shows with Earth's Dylan Carlson in July (7/26 & 7/27). Night one is on sale, night two is sold out.
