During the breakdown between verses of this show opener, Trey quietly plays a chord riff that sounds a lot like the acoustic guitar outro to NO2 from the White Tape. Trey plays the riff faster and in a different key than the White Tape version, so I'm unsure that this really was a tease, but considering that NO2 was debuted a week earlier, and would be played twice more by the end of the Summer '94 tour, it might be more than a coincidence...
