I agree with the majority here. I saw "The Grateful Dead" live in IMO some of their best years, and also IMO, some of their worst. Many of the shows I went to are the source of some of my fondest memories from that era. However, the live performance portion of the Grateful Dead experience is over, and has been for a long time. Even the surviving members of the band realize this, which is why they don't perform under the name "The Grateful Dead". The experience of that band lives on in our hearts and in our memories and in our iPods, and will for a very long time, but the live performance part of the experience is finished, never to be repeated, so expecting that is a set-up for certain disappointment.
Unfortunately, from what I have heard on archive.com, I no longer care for Bob's singing. Bob is still a competent guitar player, and Phil is still great on bass, Mickey and Billy can still play drums. But, given where I am in my life (wife and two young kids), getting tickets to concerts and taking the time away from family has become such a huge hassle, that it is not the kind of thing I can do on a whim; and this different band "The Dead" does not appear to offer enough to me to convince me to tolerate the hassle. So, I doubt I will be seeing The Dead. I hope that all who attend have a great time though.
Mama Mama many worlds I've come since I first left home.
