So, apparently, people smoke marijuana at reggae shows.

Who knew?

Seriously, though, Saturday night’s show hot-boxed the Fox Theater, big-time. The cavernous, 2,800 seat venue became one giant vaporizer tube. Even if you didn’t partake - which most of the audience did - you probably caught a contact high.

The ganja vapors certainly seemed to have an effect on the audience. Several Fox employees remarked at how mellow the crowd was, compared to the more raucous crowds associated with rock shows. Indeed, positive vibes resonated throughout the evening. Everyone, it seemed, had chosen to chillax.

Of course, the music might have had a little something to do with it, too. Following a DJ set by Massive Sound International, opening sets by the Reggae Angels and Richie Spice and a wicked dubplate throw down by Jah Warrior Shelter Hi-Fi, the Ragga Muffins festival cranked into high gear with a long set by Gentleman. The versatile German reggae artist sang, rapped ("chatted" in dancehall parlance) danced and moved from one side of the stage to another with buoyant, bountiful energy.

Another long set followed, by Israel Vibration, one of the few classic roots harmony groups from the ‘70s still active today. ‘Is Vibes’ - whose members met in a polio ward - are simply inspirational onstage. Watching them sing, their bodies supported by canes, is a reminder of how uplifting music can be. Their catalog - full of odes to Jah, irie-ness and testimonials both to the righteousness of humanity and the wrongs of inhumanity – is one of the strongest in the entire genre. They ensured their place in the reggae hall of fame with nice versions of “Feeling Irie,” “On the Rock” and “Strength of My Life,” among others.

Speaking of reggae hall of famers, few rank above Bunny Wailer in that regard. The last original founding member of the Wailers is getting up there in years, but Bunny can still bring it. Bunny looked like a Rastafarian high priest, who’d just returned from communing with Jah himself. His dreadlocks were fashioned into a natty crown, he had a red-gold-and-green headband with a gold lion covering the third eye, completing the ensemble with a white silk shirt, red-gold-and-green vest, white pants, white boots – and white sunglasses. Bunny’s easily earned the right to wear such an outlandish outfit, with a career that goes all the way back to the ska era.

Bunny’s set was replete with classic hits like “Cool Runnings,” “Ballroom Floor,” “Rootsman Skanking” and “Rule Dancehall.” He made obligatory tributes to his friend and former bandmate, Bob Marley, including “No Woman No Cry.” It was pretty much the same set he’s been performing for years. But what the setlist lacked in terms of surprises, Bunny made up for in majesty. He looked positively regal on stage, a living link to reggae history - and a messenger of the genre’s spiritual creed.

Fittingly, the evening ended with the anthem “One Love” – which made perfect sense, seeing as how everyone in the place was feeling all right.
