I think there's some truth in there, most likely, but maybe overblown. People I know involved in the scene, including members of his band, have not been all that positive about Jill's "management style" (there was that episode where Kimock left mid tour over some nonsense that got pulled by Jill who was managing the tour). But to vilify them outright, I think is beyond. Phil clearly has his heart in the right place and my friends who have played with him have nothing but good things to say when it comes to his love of the music and his appreciation for the contributions of his bandmates. Calling him money grubbing seems over the top. He plays accessible shows, including free ones, while Dead and CO was $150 a ticket for a stadium show. I also think perhaps he has no clue when he opines about Phil's opinion of the drummers (a drummer friend whose band were the Friends on a few shows was told in no uncertain terms never to bring a cowbell on stage).
Phil also got used to playing loud stages, so I can see why he plays loud. After all, he once said that his hearing was his gift to Jerry. They all played crazy loud. However, when I've seen him at TXR, he didn't seem all that loud. And Dead and Co could certainly stand to turn up Oteil. Maybe Bobby just doesn't want to hear that much bass.
I also have to ask if there ever was a "loving hippie band of brothers era" for them, really. From all accounts, it always seemed like a bit of a intense scene where personal feelings took second place to a lot of other stuff (Firing Pig and Weir back in the day wasn't very band of brotherly. Good thing they were too stubborn to leave.). Obviously, I wasn't there, but it seemed like it wasn't for the faint of heart.
It's funny, when I was watching the Saturday night stream of Dead and Co, I was thinking about when I first started seeing them in the 70s and how I kept thinking "OK, now I really know what this is! It's that!" and then would be proven wrong. What they are all doing now is still what this is and there is never a way to get an all encompassing view that would provide enough perspective to pass any kind of judgment on any of it. I can't tell the 15 year old kids seeing Dead and CO now that they missed it, because people were insisting back in 1976 that I totally missed it and there was no reason to go. Some of what I heard was as much "it" as what they played in 1967.
I did enjoy the book about Altamont, but maybe that was over the top, too.
