Or, in your mind what are people doing wrong? For me it's two things. The first is too much of an emphasis on gigs and not enough emphasis on development as a group and refining song structures. It seems like everyone I am involved with musically is just far too focused on the performance aspect of things, to the point that many just don't even really rehearse, and just book gigs. It really just tells me that people are far more interested in being seen playing music as opposed to actually playing music that sounds good. While a lot of these "live jam sessions" sound ok, they just lack a lot of subtleties that would really make them sound better. Even the jazz combo I put together some months back is starting to talk about gigs. Its all amateurs, and the goal for me with this was to just bring people together to work on their jazz skills but at least one of the people involved is talking about trying to book gigs with it and mentions it at almost every opportunity. Its fine I suppose, but playing out with this group isn't something I had on my mind, it was really just put together to work on chops. Second for me is lack of consistency and continuity in most projects. Perfect example is one set of guys thats focused solely on putting sessions together where they pay musicians to come in and play with the intent of having "awesome jams". I get it, but generally these don't work out or sound as great as the expectations are. I keep making the argument to the person putting them together that it makes far more sense to just find musicians, (even if they are at a lower skill level), that are dedicated to playing on a regular basis and improving. personally I see more benefit in regular playing sessions with a core group of people than I do in sessions with random people even if they have a better skillset. I get the reasons for a lot of this, people are busy with their lives and just want to get to the glory aspect of things.
