If You Get the Gig…. CRUSH THE GIG
It doesn't matter what gig it is, if you can get it, show what you got.
If you are in a band and even if you are way better that what the gig is, it doesn't mean you go weak at the concert. Even if that means dressing up in a bright purple costume where they can't see your face. If you have fun and show what you got, you'll get noticed. If that wasn't enough, if you are a good drummer, have fun with it! Like this person did in their children's gig. This person was awesome!
Like it says, even if you are over-qualified for the job, still go above and beyond.
