Along with a note asking you not to guess who's behind it, here's a mysterious one from Edinburgh underground imprint 〈HEADSET〉. "Optimism from 2019" (sample1) is a broken beat cut that opens with sharp minimal funk before sweet synth riffs drift in. "Reminiscing" (sample2) is mellow hardcore jungle — be sure to catch the R&B sample dropped into the back half. "Iceberg" (sample3) is electro-funk that works as a DJ tool too. Not just ravey but carrying an emotional sweetness, it's a singular record — so who could it be? (Original Japanese text by Akie)
