Wow..thats basically all i can say. I bought the cd, then realized that they were playin live like 20 minutes from my house. They put on an amazing show! They closed it with do you call my name, then went backstage. The crowd started chanting, "ONE MORE SONG!!" The drummer came out and started playing again. Then all the rest came back out and played one last song. Ra is underrated and a great bunch of guys. I got my cd autographed by all 4 and i got a picture with them. Buy From One, Duality, and SEE THEM LIVE!! My ears are still ringing.

Ex Output:

Super sound and visuals bring WWI air combat to life. For 90 years, the story of the first aces & fighter-planes has been limited to our imaginations, grainy pictures and mediocre films. Based on a true story with plenty of artistic license, Flyboys is fun to watch. An enjoyable story that puts the moviegoer in the cockpit. After watching this, you'll respect those Flyboys and be glad you weren't in the cockpit! The DVD is crisp, the audio great, the flying scenes spectacular, the story good.
