I bought a ticket just for last night because I wanted to see Loreena McKennitt. I had never heard of any of the other announced acts, but one of them did a reggae, trumpeting version of Led Zeppelin's Black Dog, if you can imagine that.
Loreena came on stage when it was almost completely dark, with a new moon. There was definitely magic in the air. Along with the usual whiffs of cigarette and pot smoke, someone near me was burning incense.
