This appears to be an arrangement of Classical Gas. And quite an impressive performance.
I'm going back to bed.
But later today, I'll be listening to 3 discs worth of Dead & Company at Alpine Valley (Night 1), while traveling to Danville, Virginia to play a show myself. That ought to cover the trip to, and from. Not counting the obligatory Waffle House stop.
At risk of starting an argument, and keeping in mind here that I'm kinda' new to Grateful Dead music, at the tender age of
<gulp> 49... I rather like the sound of the Mayer/Burbridge Dead too. It's different for sure. Oteil is much more symmetrical in constructing bass parts than Phil, but I think he does a great job keeping the spirit of the original there. And John Mayer has all he needs for the job. The only thing he isn't, is what he can't be. I like it.
