If you know what it is you’re listening for, it’s easy to hear mischievous messages in records played backwards. But it’s a bit more challenging to hear something when all tracks from the Beatles’ White Album are played simultaneously for the average song length of 3 minutes, 6 seconds. Dave Dyment, who was recently selected for the prestigious Glenfiddich artist in residence session at Dufftown, Scotland, offers this listening experience in White Noise (2005), an audio artwork in his latest exhibition “Call and Response.” It’s fitting that the show is presented in conjunction with Calgary’s Sled Island Music Festival, as Dyment is clearly a music junkie’s kind of artist. Here we see him mining pop culture and creating mash-ups that leave it to audiences to distill the familiar out of the new. Some of the other works in the show aren’t physically realized, but described in words à la early Fluxus Yoko Ono. (815 1 Ave SW, Calgary AB)
