Zer0Sum - Concrete Voices: The Mixtape. Classic White Numbered Edition.

White shell, hand-numbered, plain finish. The working edition. Built to be played, carried, lent to a friend, left in a glovebox, dubbed onto something else. It looks like every cassette that ever mattered, because that's the point. Underground music has never been about presentation. It's been about what's on the tape.

When these twenty are gone they're gone. There will not be a second pressing. Concrete Voices is a documentary in five tracks. Spoken word laid over field recordings, broken beats, and the static hum of the streets it was recorded in. This isn't an album in the way the industry uses that word. It's a tape. A document. A record of the things that don't make the news.

Across five tracks the project moves through inequality, protest, weaponised hate, and the residue left behind when communities are written off. Mrs Confidence opens it. Breath Against Concrete and Weaponised Hate sit at the centre. Unacceptable holds the line. Rust Beneath The Glitter closes the cassette, and it lives only here. Stream the others if you want. This one stays on tape.

The format matters. Cassette is the medium that built underground music when nobody else would press it. It's slow. It's physical. It hisses. You put it in a deck, you press play, and you listen to the whole thing the way it was made to be heard. No skipping. No algorithm. No queue.

Zer0Sum Recordings releases work that wouldn't survive a major label's first meeting. This is one of those releases.
