FWIW, Jimi's music suffered while Buddy Miles was allowed to adulterate it. Once he booted that clown and re-esembled the "Experience II" with Mitch on drums, and Billy on bass, they never sounded better.
Band of Gypsies was a joke. His music was falling apart in that (horrid) era of "black-funk" experimentation. Jimi was tired and worn, and allowed Buddy to have a much larger voice than he would ever had in any period that imi was in his right mind.
"Here he comes" and "message to love (a message to the universe" was written with Billy and Mitch. and it was his tightest funk stuff to me. The jam band style funk that Jimi did with the Gypsies was pure unaulterated trash. Not worthy to be re-mentioned in my opinion. What a bad marring stain to an otherwise stellar creative journey.
Now that you mention it, Dolly and other Rainbow Bridge tunes were done with Mitchell, weren't they?
