Permeable Boundary lyrics
Verse 1
Wet concrete beneath our boots
Cables snake across the floor
Four-four shudder in the iron
Pressing closer than before
You step inside my field of light
Heat rising from your sleeve
Static humming in the air
Nothing here we need to leave
Pre-Chorus
Chest to chest, the pressure climbs
Breath is slipping off the beat
Pull me under, trace the line
Where the sound and shadow meet
Chorus
Permeable boundary
Where you end, I begin
Heavy in the low-end roll
Bass beneath the skin
Permeable boundary
Nothing left between
Moving to the kick drum
Part of the machine
Verse 2
Strobe flash freezes on your neck
Drops of water turned to glass
No more room to step away
Watching every second pass
Finger traces on my wrist
Pushed against the speaker wall
Tremor running through the ground
Neither one afraid to fall
Pre-Chorus
Chest to chest, the pressure climbs
Breath is slipping off the beat
Pull me under, trace the line
Where the sound and shadow meet
Chorus
Permeable boundary
Where you end, I begin
Heavy in the low-end roll
Bass beneath the skin
Permeable boundary
Nothing left between
Moving to the kick drum
Part of the machine
Bridge
No outside
No yesterday
No border left
To wash away
Just your pulse
And the steel below
Only one way
This can go
Chorus
Permeable boundary
Where you end, I begin
Heavy in the low-end roll
Bass beneath the skin
Permeable boundary
Nothing left between
Moving to the kick drum
Part of the machine
