There's a bump in the basement
There's a knocking on the wall
In the pumping of the piston
I swear I heard your call

There's a bump in the basement
There's a hole in the floor
There's a guard in the garden
Locking up the door

There's a rumble in the floorboards
No shutting out the sound
And the workers are below me
Digging underground

Feel the building all around me
Like a wrap of armoured skin
But the more we are protected
The more we're trapped within

Tell it like it is, till there's no misunderstanding
When you strip it right back
Man feed machine, machine feed man

Tell it like it is, till there's no misunderstanding
Make up what you like
Man feed machine
Machine feed man

Brick by brick
By brick
By brick
We're building
...
