The workings of my brand new organ

Seems you've been chasing air,
And it's something that you can't hold onto.
But it's this question that i ask,
Who's that singing in the alley?

So, I'm left wondering,
Where everyone went.
Sitting here, Watching
Waiting.
Listening to the sound.
Thats ringing between my ears.

As this machine records,
It captures all we're trying to hide
