content: This is not a true DVD-AUDIO... normally, the point of a DVD-A formatted disc is to remix the original album in 5.1 surround, playable on dvd-a players or dvd players with 5.1 surround sound.This is NOT the case... this is merely a higher quality recording (higher bit-rate) disc of a classic coltrane album.If you don't already own this album, you should get it. but if you already own the "regular" cd, this is not what you probably want.
