I want my neighbours to know that The Who exist.
A drum kit would, but an electric drum kit would be perfectly quiet. You can't hear an electric guitar from more than a few metres away, and bass even less. You basically have to be standing next to it unless someone is slapping the **** out of it.
I'd worry more about vocals, but if all they hear is singing and some drum pads being hit then that sounds pretty quiet.
An unamplified electric drum kit generally sounds like someone whacking a book with some sticks. Not normally a problem unless you are in the same room. Belting out death metal screaming vocals with no audible backing music may be slightly more irritating for those next door.
