I know you are tight with Mark Turner, who he is also tight with, but wonder if you have played with him. I don't know if he thinks upright is the hippest form of bass, because he's not recorded with electric.. but at this point I'm just speculating.
IMO he is completely cutting edge but never loses the ability to stay melodic. Favorite guitar player on the planet right now.
Opinions and experiences with Rosenwinkel?
