Half-Life 2 — Lab Practicum (Bridge Music)

Kelly Bailey scored Half-Life 2 for Valve in 2004, largely on synthesizers and samplers rather than live instruments, which is why it sits somewhere between industrial, ambient, and film score. 'Lab Practicum' is one of the quieter cues — a slow pad-and-drone piece that the game triggers as Gordon Freeman edges across the wrecked suspension bridge in the Highway 17 chapter.

It's maybe ninety seconds of music in the game, looped and stretched here into something you can actually sit with. The bridge sequence is all vertigo and wind, and the track leans into that with almost nothing happening: a held tone, a few detuned swells. I keep it on for writing when I want tension without a beat pulling at my attention.
