Query: Yes-Live at Montreux

To all serious yes fans. If you own a blue-ray player you need to purchase this disc. Absolutely an awesome concert experience with a quality surround system. Being a Yes freak for thirty years i can only say this is one their best performances on disc to date. Incredible picture and audio. Running through a PS3 to a onkyo surround with klipsch tower fronts. INCREDIBLE!!!!!!!!!!!!!Looking foward to seeing them in 2008..
