Not bad, I see efforts put in here and I like the premise. To me this seemed too long for a pilot and inconsistent plotwise. The starting point is they need a drummer, but in the end they don't find one, instead we have the introduction block that was not really necessary because we have them introduced via their dialogues. I'd suggest having only the introduction part and some more music for the pilot and looking for a drummer as a complete first episode with actually finding one maybe.
