Sleep: Dopesmoker: 2xLP Black Vinyl
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 a full-length 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.
