Dopesmoker - Sleep - Recorded in 1996 and not released (in slightly different edit/mix) until 1999 under the title Jerusalem, the legend and lore behind Dopesmoker would overshadow an LP of any lesser significance. But the 63-minute magnum opus dedicated exclusively to the sacrament of marijuana is not just the pinnacle of the goofily named stoner metal genre... it's inarguably one of the most important and influential albums of all time.
