Instant gratification is an interesting title. The Internet makes it so easy to get hold of the music almost instantaneously and communicate/dissect it...it's so easy to instantly analyze today,and phishs music is made for nerdy dissection, on some level.
On another level, you can't dissect pure joy...and you could feel that from the band, crowd, etc...a great jam and a supreme moment...well said @johnnyd
The interesting thing about instant gratification is that phishs most gratifying moments aren't instant at all; they take patience from all involved even though you get multiple moments every night. The collective cognition that this was perhaps the moment of recent years is just fun to know about/be apart of. WOW.
