I believe the BT and Flaming Lips DVD's I referred to were DTS recordings and definitely a nontraditional approach to 5.1. The Flaming Lips would have made Timothy Leary proud, if the audio effects weren't enough, one of the songs video was just colored balls falling. BT was instrumental and Techno type music. If you are open minded and into a new 5.1 experience you should check out one of these.
