The riff is there almost before anything else, and it never leaves: a low, buzzing guitar figure chugging against a light drum tick, steady as machinery. Within two bars it has stated the whole bargain — nothing in the next three minutes will alter this motion. It's a train chug before a single word names a train, a one-chord stomp that takes the body early and gives it somewhere to sit. Then the voice comes in low, just past ten seconds, and it's less singing than a man moaning into the room: smokestack fire burning gold in the dark, and already the question underneath everything — why don't ya hear me cryin'.

Every verse runs two or three lines, and then the voice quits words for the whoops — that climbing whoo-hooo is the true refrain, the sound the record leaves in your skull. The verses work like visits: a new question each time, the same cry returning after it, as though the question changes but the ache never does. His phrasing rides loose over the chug, half-spoken, syllables dragging behind the beat and leaning across it, while the guitar underneath sits dead level. The words wander and plead; the riff keeps time and ignores them, and that friction is the whole drama.

Nothing thickens. That's the quiet surprise of the middle stretch: where a band would pile on, the surface stays thin and open, and the record simply rotates who speaks. Around 1:00 a harmonica steps forward with bent, wailing notes — the first new color since his own voice walked in — hollering back at the singing like a second Wolf, then folding back into the chug. The verses keep turning too: what's the matter with you, where did you stay last night, and finally the plea names the machine the riff has been all along — stop your train, let a poor boy ride. Small gusts of low-end weight pass beneath, but the floor never shifts.

The farewell verse — never see you anymore — tips its trailing whoops toward something close to release, the one place the crying sounds free. The last verse turns jealous, wanting to know who's been around since he's been gone, then drops the whole thing with a muttered girl, be on — and that dismissal, laid over the same unbroken stomp, cuts deeper than any holler on the record. Because the chug itself never moved, every shift in the voice arrives at full weight.

The pressure finally eases around 2:50, a small exhale after three minutes of held breath; the last phrase drops back, and just past 3:00 the body's hold loosens with it. What remains is a single chord left hanging in the air, ringing and thinning until the track lets it go. No tag, no reprise — the train recedes, and the smoke clears out of the room.
