I second the vote for Gallows Pole

Have to go with a top 5 here:

1. In My Time of Dying
2. When the Levee Breaks
3. Celebration Day
4. Achilles' Last Stand
5. Ten Years Gone

When the Levee Breaks and The Battle Of Evermore.

No Quarter is also an awesome song, but Tool's cover of it is far better than the original version.

These five in no order:
-Stairway to Heaven (yeah, I know...)
-Achilles Last Stand
-Kashmir
-Battle of Evermore
-Over the Hills and Far Away

I'll go with Achilles Last Stand.

The Rain Song

this!

In my Time of Dying. Epic
