This Toronto-based singing group led by Nobu Adilman and Daveed Goldman takes a unique approach to the concert experience — and to having a band in general. They travel around, occasionally singing with the likes of David Byrne, Patti Smith and Debbie Harry, but mostly assembling a group of strangers in a room, that being the audience itself, handing everyone lyrics, and transforming them into a spontaneous choir that somehow comes out sounding incredible. For this particular show, it’s all 1980s hits. We’re talking Prince, Madonna, Bon Jovi, George Michael, Journey, Whitney Houston. Imagine, a hundred people hitting the high notes on “Living On a Prayer” in glorious unison.
