Even if he had never progressed beyond the brain-rattling riffing of "2112" and "Xanadu," Rush's guitarist would have left his mark on Metallica and other like-minded metalheads.

Alex Lifeson reserves his most daring playing for his solos – just try wrapping your head around the extra­terrestrial lunacy of "Freewill."

Key Tracks: "La Villa Strangiato," "The Spirit of Radio"
