Query: A rave for the non-drug crowd

I recently saw the Blue Man Group (BMG) in Las Vegas, fulfilling a 5-year ambition to see them. Other reviews describe them well--percussive and avant garde. While taking a taxi to another venue, the cab driver challenged us (his words) to describe what BMG was about, and I was unable, until I thought about it later. To me, the group is about bringing rave culture to the mainstream, absent the drugs. The show itself is a full multimedia mind-blowing experience, one that needs to be seen to be fully appreciated. As such, the CD, while excellent to those who have seen the show, may seem cold and lacking to those who haven't. For me, it brings back fond memories of an act I truly enjoyed.My recommendation is simple--see the act first, then buy this CD. Buying the CD first will only leave you scratching your head.
