I like to think of bands as stages of my playing history, as I become obsessed with one band or collection of bands at a time. As such, this is the general history of about five years of playing:
0-1: Nirvana, Led Zeppelin, and Refused.
1-3: Death Cab for Cutie, Bright Eyes. This is also the span of time that I began actively writing my own material.
3-4: Islands, Rilo Kiley, Beatles.
4-5: RADIOHEAAAAAAD. And I'm also running another creative period. Lots of original jams and stuff.
As far as jargon goes, I'm pretty into progressions featuring major-sevenths (reeeally relaxing effect) and I'm starting to incorporate more percussive techniques into my general playing style (harmonics, slapping, knocking on the strings every so often for a beat, etc).
In general, I've stuck to acoustic. However, following a jam in which my friend played a string of hardcore/hard rock rhythms and I had no idea what to play over them, I've been dying to get a feel for heavier stuff.
