What rock group has four men who don't sing?

I have a handle, but handling me doesn't have anything to do with me or my handle these days. But let's not focus on that - let's move the camera over to examine another one of my meanings: to criticize, which is what would be done to you if you didn't move the camera smoothly.

A made up word for everyone in our world. It begins with something to contain coffee or beer, followed by the last three of the US’s mighty bird.

I have teeth but don't eat. You can put something into me, but I'm not a container. You can switch multiple of me, but I'm not a toggle. I'm irritating when someone grinds me. I'm preparing for something when I'm up. I'm preparing for landing when I'm down.
