I feel for you guys. I've been very lucky and have a really fun time rock'n'roll/hard rock band. Although we've got pissed often enough, our singer never drinks, and we have the luxury of a free practice room where we spent most of today writing a new song "Dynamite" - yes we like making noise and turning it up to 11! :P
I know this may look like I'm rubbing it in, but I'm in such a good mood atm, and basically wanted to say that there are other people into (well, what I call) decent music although they may be hard to find....
If I didn't have the band though, i doubt I'd put as much work into my guitar playing and sound. It's hard to motivate yourself I find....?
