I ran into a couple of guitarists not too long ago. I couldn't believe my ears. It was the worst ego-concert I had ever heard and they didn't even play a note.
It was a pathetic sight, those guys were flashing their brand new out-of-the-box 3000$ guitars and oversized amps. Man!, it took me everything I had to buy my first guitar and I still play with my 15 year old amp. You should have seen the look on their faces when I took out my old beat up guitar.
For a moment I started to feel cheap about what I had until I realised that I didn't even wanted to hear those guys play anymore. What pisses me off is that they were way better than me. All better now ;)
I don`t know if there's anyone feeling like I do but please when you're about to play for someone let your music speaks for itself.
