[Verse 1: Undercutting corundum-rib male rock singer, undercutting] Rail cold under a palm that knows every fray I carry gauges and timing and a list of every stay Top tank holds the first air, I seat and pass it on Evening crew waits on my hiss before they cue at dawn Hands on the valve, lungs full of dust and chalk Headset dead for hours, so the voice becomes the walk I do not own the shop, I own the middle span If my tank blanks out, the whole shift loses plan [Hook: Undercutting corundum-rib male rock singer, loud, undercutting] My tank hisses so their first tool can trust Not a speech, a timing they can prove and thrust Grip the valve, mark the eight, send the next one through Shop holds only if the middle tank is true [Verse 2: Undercutting corundum-rib male rock singer, colder, undercutting] I learned the mark from a runner who left no name Only a worn bleed chart and a habit that became the game Tonight the valve slips like a quiet dare I feel the slack before the house lights care Stacked guitars wait on my mouth to land the seat I sing the hiss they need and keep the line neat No banner, no speech about pride or the past Just valve in my hands and a mark that has to last [Bridge: Undercutting corundum-rib male rock singer, tank hiss, undercutting] Tank hiss seats under my palm Guitars stack hard on the calm Evening crew never sees the slip They only feel a shop that will not tip [Verse 3: Undercutting corundum-rib male rock singer, undercutting, louder] I finish the row with chalk still on my sleeve Leave the chart folded where the next shift can believe Boots on the deck already testing the give I hear the first tool kiss and know the tank will live Undercutting through the last hiss like a vow with no crowd Loud enough for the valve, quiet enough for the cloud My job is the middle, not the whistle or the board Hiss seats, air holds, that is the whole reward [Hook: Undercutting corundum-rib male rock singer, loud, undercutting] My tank hisses so their first tool can trust Not a speech, a timing they can prove and thrust Grip the valve, mark the eight, send the next one through Shop holds only if the middle tank is true [Outro: Undercutting corundum-rib male rock singer, proud cold, stacked guitars ring out and fade] Tank hiss, Saturday Tell the shop I said stay [End]
