Whereas the single version of BU2B that was released last year kicked down the barn door without warning, now it begins with lightly strummed acoustics. The main riff is just as smashing, however, a growling, grinding earth-mover over which Lee sings, "I was brought up to believe the universe has a plan/ we are only human, it's not ours to understand."

Most bands would stay right there, but Rush keep tossing the ball around - Lee and Peart lock in during the bridge at full gallop, with bass and drums pulsating and bubbling.

A solemn, vaguely religious tone builds - Lee's vocals take on a choir-like cadence - and then Lifeson uncorks a brief zinger of a solo - stabbing, thrusting notes that thrash the listener about before smacking headlong into the final chorus.

A tough, forceful rocker that works its way into the thicket of your senses.
