Recording music since '93, Si's catalogue of music has always pushed the boundaries of dance movements of the day: electro, breaks, garage, bass, techno and almost everything else. With a weird and wide-ranging career that includes a 2004 Peel Session and music put out alongside Tipper and Neil Landstrumm on labels like Tresor, Fuel and Novamute, Begg has proven himself as one of the true greats of the sound. Focussing his career on TV and film in recent years has meant a slow-down in the rate of bangers making their way outside of Begg's studio but '400 Million Pieces of You' shows that they are still very much being made, and are perhaps bigger than ever in their magnitude.
