It’s hard to think of a more ubiquitous topic in reggae than ganja. Now Greensleeves collects 18 joints, old and new, as a spliff-rolling soundtrack. The tracklist spans the eras from roots to dancehall, but offers few surprises: Triston Palma complains about people who continually ask him for Rizlas and lighters; John Holt, Eek-a-Mouse, Barrington Levy, and Carlton Livingston evade Babylon; Bounty Killer claims herb “makes you feel constructive and brave”; and Wayne Wonder & Don Yute take a stoned joyride. Nevertheless, it’s a rich harvest of cultural reggae tunes even non-smokers will find irie.
