i think in any genre there are waves of styles that come and go and morph into others... a style will get comfortable until someone comes along to shake it up.. then people start shifting to something new, and then that gets done for a while.. and then it shifts again. it's been that way forever, i suppose.
i know for me, personally, i just sort of ebb around and settle into ways of composing for a while. sometimes i'll hit on something that is sort of fresh, and sometimes i sit in one place for a while.
i'm a firm believer that there's nothing new out there, at least to the point that i don't consciously try make something that sounds "new" i just want to make what's new to ME and keep exploring new areas that i haven't before. whether or not people like it is another story, and one i try not to worry about too much. although it's difficult to detach from that completely because of 12k and working with other musicians and stuff.
the same applies to 12k, really. it goes in waves, settles on something for a while, then moves. and, every now and then i like to throw a curveball in for people, hopefully keeping it interesting.
