The only problem with the statistics is that they don't reflect HOW these bands played over the respective years. Does Phish 2.0 have the equivalent value of The Grateful Dead's last few years as some would suggest these were these bands 'less provocative' years?
How about consistency within these years? I've seen lots of Dead shows; some incredible others forgetful. I've seen lots of UM and moe. shows and none were ever as bad as the worst Dead show I ever saw; and none were better than some of the best Dead shows I have seen. Phish has their lulls (ie 1/1/15) but I have never seen a totally sucks Phish show.
