“It’s a heavy-hitter. It’s dark and a little out of character for Rush. It went through something of an overhaul from the version that was put out last year. We added the intro section that Neil always envisioned. Alex and Geddy actually recorded that in their hotel room.
“Like Caravan, this one was quick – we spent a day on the drums, then immediately did the bass and guitars. After that, we did overdubs. We did Taurus pedals, and we did a theremin, too. That really cool, squiggly, ascending part in the middle is Geddy playing a theremin.
“They had one in the studio, just lying around in Blackbird – it’s such an amazing place, the things you find there. So we took the theremin, plugged it into an amp, put some delay and a phaser on it, and he did a solo. I think he might have played one back in the ‘70s. His performance is cool. He did it once and it worked out great.”
