Tri Angle is one of the hardest labels to pin down in contemporary music. Even before its first proper release it was issuing enigmatic manifestos and mixtapes online, and since then it has brought together lone laptoppers from the Middle East to the Mid West, flitting between bedroom/basement lo-fi and the honed sonic techniques of the R&B production line. Even the label itself moves back and forth between London and New York every half year. Label boss Robin Carolan is in the studio this week to talk through the roots of this most rootless label, from the cyborg Auto-Tune of Britney Spears's lost years through the sonic fictions of Ghost Box and the glossy exoticism of hiphop producer Bangladesh. Resonance FM, Thursday 26 July, 21:00-22:30.
