IMO the Allmans have an incredible rhythm section. I've seen them often over the years, and they are as good as they ever were. I personally would prefer Wolf or Muddy or John Lee or whoever, but they are all dead. BB's still here, but he's phoning it in, and I can't blame him. I do see Buddy Guy whenever possible.
So I watch what I can, and I'm glad there are still youngsters coming along who appreciate the music and want to play it. And just like us when we were young, some of the kids today will eventually realize that their pop stars are covering older songs, and they'll track it back through the white rockers to the black originals. And they'll gather appreciation for the new guys carrying on the traditions. So the audience will be there, even though the paparazzi won't know who they are.
By the way, when I do see Buddy Guy or Keb Mo or the Allmans, there's always a significant percentage of younger folks in the crowd.
