If you could keep ONE album from your collection. . .

The setup
You're stuck in a van for three weeks (visiting a National Park in every state (that has one) in the CONUS). The van has no radio or aux input. It does have a single compact disc player.

The rules
Due to space constraints you can only pick one and only one CD or album (burnt to CD) from your current collection
One CD means one CD: obviously no box sets
It cannot be a compilation (aka mix) of different artists.
It cannot be a compilation (aka "best of") of the same artist
It cannot be a collection of covers, e.g, must be original work of the artist in question.
Format: Artist - Title

I'll start:
Falling Up - Captiva
