Though a badass, pulsing nightclub isn't one of the first things called to mind when one thinks of Colorado, Denver does boast a superclub that, while seemingly misplaced, has made a name for itself when it comes to green partying. In addition to the use of sustainable materials to erect its club-in-the-club, Beatport Lounge, recycling centers at major traffic points ensure that every last embarrassing cranberry vodka cup ends up in its right place. For those requiring a quick minute to recuperate, a 5,000-square-foot botanical garden invites revelers to chill out and regain their hearing in the midst of Boys Noize and Digweed shows.
