Verse
Valve cracks open under the curb
Pressure climbs where the pipe bends
Iron lung beneath the avenue
Fills the dark, then empties again
Gauge needle jumps to red and back
Steel drum shudders, floor plates ring
Every block waits for the next release
Concrete flexes with the swing
Pre-Chorus
Fill the line, hold the beat
Who decides when the city breathes
Chorus
Concrete systole, pressure through the vein
Concrete systole, rising, drops again
Concrete systole, pulse beneath the street
Concrete systole, we move to what we can't see
Verse
Manifold hisses behind the wall
Copper joints keep the count in time
Pump house shakes on the half beat down
Sends the surge up the risen line
Sidewalk grate breathes a heavy sigh
Vapor climbs where the pistons meet
Nobody sees the chamber below
But everybody moves to the beat
Pre-Chorus
Fill the line, hold the beat
Who decides when the city breathes
Chorus
Concrete systole, pressure through the vein
Concrete systole, rising, drops again
Concrete systole, pulse beneath the street
Concrete systole, we move to what we can't see
Bridge
Valve open
Valve shut
Pressure up
Pressure cut
Line full
Line bare
City breathes
We're the air
Chorus
Concrete systole, pressure through the vein
Concrete systole, rising, drops again
Concrete systole, pulse beneath the street
Concrete systole, we move to what we can't see
