Verse 1
Black grease on a rubber sole
Sub-kick in the collarbone
Four a.m. and the vapor clings
Copper wire on the speaker rings
Pre-Chorus
Count the kick, watch it climb
Running out of borrowed time
When the ceiling starts to white
We stay buried in the night
Chorus
Pound it down on the iron floor
Feed the dark till we need no more
We don't stop till the lights come up
We don't breathe till the lights come up
Pound it down on the iron floor
Heels locked in till they clear the door
We don't stop till the lights come up
Iron floor, iron floor
Verse 2
Cold sweat on the temple seam
Cut right through by a single beam
Teeth grit hard to the tempo grid
Keep the pressure under the lid
Pre-Chorus
Count the kick, watch it climb
Running out of borrowed time
When the ceiling starts to white
We stay buried in the night
Chorus
Pound it down on the iron floor
Feed the dark till we need no more
We don't stop till the lights come up
We don't breathe till the lights come up
Pound it down on the iron floor
Heels locked in till they clear the door
We don't stop till the lights come up
Iron floor, iron floor
Bridge
Cold steel
Hard lock
No sleep
No clock
Hold ground
Stay low
Nowhere else
Left to go
Chorus
Pound it down on the iron floor
Feed the dark till we need no more
We don't stop till the lights come up
We don't breathe till the lights come up
Pound it down on the iron floor
Heels locked in till they clear the door
We don't stop till the lights come up
Iron floor, iron floor
