There are some brilliant ideas there, and some parts that have cool sounding pianowriting but lack memorable melodic material, I suppose this is always the risk with improv because you can rely on core techs and harmonies but you canāt rely upon inspiration striking all the time. This is why Katās ācomposed improvsā based on stellar pre-established melodic material fleshed out in new pianistic clothing seems like a great idea.
