Forget any other rock instrumental you've ever heard. This one blows it away.

This is the closing track off Rush's "Hemispheres" album, performed live. Watch the video and realize: this is performed live by only three guys. No mistakes, only awesomeness and pure music.

I think this song more than any other showcases the sheer talent of Rush across the board. Alex is often left out when talking about the great guitarists of the world. When compared to Neil and Geddy it's easy to see why. This song lets him show his stuff.
