FIND YOUR SOUND - and start from within.
Sound a little cliche'? Maybe.
But what would happen if you obsessed over your sound, your voice, and your message as much as you do when you're mixing a song or buying gear?
And I don't think this is exclusive to original artists. There's still PLENTY of room for interpretation in tribute and cover bands alike.
Take your time, experiment, be intentional, and you'll be miles ahead already.
