Asian Dub Foundation formed in 1993 as an outgrowth of the documentary Identical Beat, a film shot at London's Farringdon Community Music House, the site of a series of summer workshops designed to teach Asian children the essentials of music technology. In charge of the workshops were tutor Aniruddha Das and youth worker John Pandit, also a noted DJ; with one of their students, a 15-year-old Bengali rapper named Deedar Zaman, they soon formed a sound system that they called the Asian Dub Foundation. After each adopted an alias they gradually evolved into a working band with the 1994 addition of Steve Chandra Savale, an innovative performer known for tuning his strings to one note like a sitar.
