and it was one of those jam on a chord, or a riff, or a 1-4-5 hypnotic groove on a 10 minute beat thing etc... basically whatever comes to mind. After about an hour or so of that, we were talking and having a beer. One guy talked about improvisation and the other guy said we try to repeat something we did last time and it's never the same. They asked me what I thought. I said that it had been a very long time since I'd been at a freewheeling jam like this, and it was kinda fun. I said I usually play songs. They burst out laughing! I laughed too and it blew my mind.
