I bought a dvd-a disc "Vivaldi four seasons" and it sounds great! really big difference listening to dvd-a and regular cd. I saw also that the store was selling led zeppelin in dvd-a. How can this be when hes cd was recorded in the 70's???? Information This 2-disc DVD-Audio album contains the original 18 live-tracks. Containing two and a half hours of live rock, 'How The West Was Won' contains performances recorded during two concerts at the Los Angeles Forum and Long Beach Arena on June 25th and June 27th 1972. These recordings were produced by Jimmy Page. Exclusive colour photos of the group performing live on stage introduce each track. There are also options to choose between 5.1 Surround Sound and Stereo playback. How is this possible???
