“I think we were going in a different direction with Halo Effect. I remember we were in our little control room – we had three different rooms going at one time – and I picked up an acoustic and started playing. Geddy began mouthing the lyrics, and then something clicked: he started playing along, and we just developed the song from there.

“The song is really about the emotional decisions we make that don’t work out. Quite often, it’s in a relationship – you think you see something, but it’s not really there. So the song had to be sweet and it had to be heavy at the same time. We needed those two contrasts. I think we nailed it.

“There’s such a great acoustic sound on it, and the solo section is something that’s quite different for us. It’s frivolous and light, kind of like butterflies in your stomach, that feeling you get when you’re in love with someone you shouldn’t have fallen in love with.”
