BB Bleu was originally demoed by Kid A herself, but was picked up and properly produced by Pierre Serafini, AKA Opti. The France based producer and boss of bass music label Airflex Labs loved the original demo (included on the single) and worked on it along with Kid A's initially internet-procured mentor and musical soulmate, the French techno producer Agoria. Its sparse, icy drums and warmer, textural melodies provide the perfect backdrop for Kid A's yearning, personal musings on desire. It's like a rainy-day French blues played through modular synths and transposed into US soul.
