The first time I played Factory Floor's new single, Heart Of Data, I wasn't too struck on it. I must not have been paying attention because it is 6 minutes of sleek modern techno brilliance. Pulsing bass, waves of synths, crashing cymbals, kick drum and a sense of rushing to meet the future. It and the B-side are from their score for Fritz Lang's 1920s sci fi classic Metropolis, which they produced last year for the Science Museum. More please.
