In the spirit of Nachtmystium and their hints of Stoner Metal, I bring some of the best Stoner Metal I know of. Electric Wizard has a definite influence from classic Psychedelic Rock and "have a distinct yet traditional doom metal sound that incorporates Stoner and Sludge traits." Epic, slow and heavy makes in an intense ride... a band to check out! Wild stuff while smoking*.
*I do not condone or suggest illegal drug use... do not blame me ;)
