Credits

One record at a time, and the reason for each step.

Bay Area Thrash Metal

Riffs cut like machine tools, tempos past 200bpm, and a garage circuit that rewrote American metal.

West Midlands Metal

Downtuned riffs from a factory city — Sabbath to grindcore, four decades of Birmingham making music heavier.
