Sleep and Gimme Metal have teamed up to present the Sleep 420 Dopesmoker Special, which will see the online streaming platform host an exclusive 24-hour playback of Sleep’s seminal album Dopesmoker on April 20. Since the album is not available on streaming services, this is the only way that fans can stream the album while partaking in this year’s 4/20 festivities.
