I didn't take any photos this time in Montreal, but here's an old one from when I was exploring a little more of industrial photography. Not a direction I ended up going, though I though about it seriously for a while. Maybe there's another universe where I'm going around to factories and photographing them.
This is from one of the Port of Montreal's last remaining large grain elevators, which has been repurposed as a giant musical instrument - you can talk or play into a microphone outside and hear the sound resonating through the whole structure. I doubt these pipes have much to do with it, though.
