On 4/20, Sleep fans had more to celebrate than bud as the band released their first album in 15 or 20 years, depending how you look at it, with The Sciences. Today (23rd), the band surprised us once more with the release of their new song “Leagues Beneath.” The track was premiered via Adult Swim’s Singles program and it is separate from their latest record. One could say, you could Sleep for 17 minutes (16:44) by getting lost and mesmerized in this extended tune.
