jammed in too tight

So, I’m in this band, Concentric. I began it about 5 years ago as an outlet for my “songwriting.” Yes, the quotes around songwriting are intentional. When you write instrumental music, you sometimes feel that you’re not really writing music even though it may be more complex than vocal music. When are you done? Has the theme gotten to repetitive? Has the intended emotion of the song been communicated?
Anyway, once you get your head deep into songwriting, it becomes like any other creative outlet – you start to become over-sensitive.
In the latest incarnation of Concentric, we’re doing a lot of simultaneous cooperative songwriting – basically jamming -free of any borders. A free jazz jam isn’t always that free with me. I can’t help myself sometimes – I get too concerned about trying to write more structure on the fly. Here are two snippets from our last jam where about 2 or 3 minutes into it, I’ve found a phrase, I can’t let go – I’m jammed in too tight.
Here’s a first sample…another short spring Austin went from freezing to 100F in a matter of 3 weeks)
Here’s the second…where you’re from (a random title, a brooding tale of your troubled youth – you are haunted)
Anyway, being jammed in tight is not bad for the bass player (that’s me), that’s because humans like the bass simple and repetive. Almost always – from rap to punk to classical. Why, I don’t know – some biological reason? a repetition of a low pitch snore that comforts you as a child?
