I like it too. Often his improvisations across instruments were very, pardon the contextual pun above, "fluid" so it seems like no matter what others were doing, it fit in. I think of someone like Daniel Carter who switches between tenor, alto and soprano saxophone, trumpet (on which he has a beautiful sound), and sometimes piano (if one is available). Instruments are tools to express a given set of ideas and if they're used to their expressive potential, who can argue?
