In the terminal phases when all noteworthy popular music pushed at the extremes before an inevitable collapse, Sleep stood tall by offering up Dopesmoker, an album comprised solely of its 64-minute title track. Extending Sleep’s psychotropic mythos to evoke a mystical journey through stark alien lands in pursuit of transcendental intoxication, Dopesmoker takes heavy rock to its final destination, where only those truly dedicated to madness, distortion and brain-bending phantasias were left to guard the crumbling ramparts of reason.
