Rising British metal stars Green Lung thrilled a sold-out audience in Toronto Tuesday for the band’s first-ever show in the city — but on this night, the crowd’s biggest round of applause might not have been for the band at all.

It’s not like the quintet disappointed — far from it. Seeing the stoner/doom band live feels a lot like what it must have felt like to see Black Sabbath in the early 1970s, with a vivid, unbridled power coupled with dizzying musicianship and occult themes.

But Buffalo resident Jacob Marsh might have stolen the show when he got on one knee on stage at The Velvet Underground mid-set and proposed to his longtime partner, Jared Pease, causing the crowd to absolutely erupt.
