Interested to hear this as well. I'm a big fan of them with Frusciante, I love the little jams with him and Flea between songs live. I belive this band is really gonna miss the musical chemistry between John, Flea and Chad that they built through the years, especially since the reunion. Hopefully I'm wrong though and this new guy impresses me.
Side note, has everyone seen this jam of John, Flea and Omar Rodriguez? Amazing. http://www.youtube.com/watch?v=HFDdIIITJ08
