sometimes you cant tell by listening to something how it was composed or not composed. like i forget who it was, somebody nerdy, mighta even been greg, i was talking to after seeing orthrelm, and he was saying how its amazing he plays his set spot-on the same way every time and hes got it all written out or something... but it would also be believable, if you only saw them once, that there were certain things that were planned, and others that were subject to variation within that structure and that it was jammy, and you wouldnt know whether or not that was the case. and sometimes ive seen people who are definitely jamming, because they werent really a band and they had some guests step up with them who never all play together, play a jam that went somewhere amazing, and you would have sworn theyd have to plan it for it to end up where it did, but hey, they didnt. so when a lot of people who arent performers discuss music, they might call something jammy to describe a certain mood or sound and everyone knows what theyre talking about, even if the musicians were in fact jamming or not.
