Good Grief where do you start.
It would depend on a lot of things, would it be classical, rock, new wave or what, but here goes.
Barbers adagio for strings
Vide cor meum (the Opera scene from Hannibal)
Wagner Die Walkure
Moonlight sonata
Or
Just about anything by Pink Floyd, but especially Shine on
or Keep talking.
Rammstien, Fire Fire
The Disturbed, Down with the sickness
Or
Mike Oldfield again just about anything but especially Sunjammer, Tubular Bells 3 the man in the clouds.
Even Terry Oldfield (Mikes brother) Wings of the Morning.
But if I brought my iPod, I could have all of the above and just about anything anyone has mentioned so far too
including the wild morning, SimonM just mentioned.
Even a bit of Ozric Tentacles
.WHO??
Far out man.
