If you want a great acid trip of a an album, download Brainticket's Cottonwoodhill.
It's semi-krautrock, but beautiful riffs, and the last three tracks slowly build upon each other with this female voice describing the most intense acid trip.
It's a very good album, and very nice to smoke to.
Uplifting too.
Another good (but not nearly as good as cottonwoodhill) album by brainticket is Psychonaut.
