In the March 2004 issue of Guitar World
magazine, Alex Lifeson explained the bizarre-sounding harmonics heard before the solo: "I create them by playing off the pick and my thumb. I hold the pick so there's a slight edge of it showing between my thumb and finger. This allows my thumb to mute the string, and that's what causes the harmonic to ring."
