You might like to try John Cage's 4'33". You don't even need to take the cd up there with you :) Sitting there and concentrating on hearing what's at a site is one of my favourite bits of being there, it means I've finally relaxed and I'm properly there.

(any similarity with this sounding like me being a pretentious git is completely coincidental, that would be the opposite of its intention)
