Currently going through one, big time. Feeling really lost and stuck for inspiration. I know where I want to go, and how I want things to sound, it's just not moving anywhere. I keep writing new riffs, feeling like I'm onto something, then listening back and going "nah" and trashing them.
It doesn't help that my band is really stuck in a rut at the moment. We've decided to move away from our current stock of songs, and that style all together really, as we've sat on these tracks for months now whilst auditioning vocalists and what not, and it's that whole syndrome of over-exposure, and feeling disenchanted with the way things are moving. It puts a bad stink on what you were initially excited about.
So after a brief band meeting the other night, we were all in agreement that it's probably time to start a fresh, perhaps ditching the idea of waiting for a vocalist, and me stepping in to cover those duties as well as guitar (at least for the time being).
It was one of those conversations that was uneasy at first, then escalated into excitement and creative fever. I left feeling really inspired, new pastures, blank canvas, and other clichés, ready to pick up my guitar and just riff like a bastard, start writing new songs, I couldn't wait!
...And ever since then, for the last 4 nights, all I've done is sit here with my guitar and delete riff after riff after riff .......
Play for the sake of playing. You can get wrapped up in the "everything you do must be a song" idea when you play with others alot and sometimes just playing the freakin guitar without an agenda can help quite a bit. They all cant be songs, only the ones that stick, and if they don't stick..bye bye. All killer -no filler is a tough road but worth it I think. Just play man, no songwriting, as weird as that may sound right now.
