Yes, the Dead’s jazz influences don’t show up as consistently as with the ABB, probably because their music encompasses a lot more different musical styles and genres. But you can certainly hear it in songs like Eyes of the World, Bird Song, Crazy Fingers, and some versions of Dark Star. And the band would swing a lot more when Kreutzmann was the sole drummer for a few years in the early 70s.
Sure. I don’t contest any of the above. Comparing the Allmans to Jerry and the boys, I meant, overall. I much prefer Kreutzmann on his own. IMHO, he didn’t need any help! Like Mitch Mitchell, he has a "slippery" feel. I prefer this approach to heavy handed "bashers".
