OAKLAND, Calif. – Hundreds of audio cassettes sparkle like jewels in red felt-lined flight cases. Stacks of Soviet-pressed vinyl records bear liner notes in Dari, Russian, or English. No two are alike – the covers are bold, technicolor things with holographic sheen and vivid script. The music itself feels uncanny, a stream of tablas and horns, electric guitars and synths. Modern sounds recorded on grainy, antiquated equipment.
