From BBC NEWS:

A demo placed on the internet has triggered the initial success of one of China’s first hip-hop groups, Hi-Bomb.

Hi-Bomb – composed of Lionel “Little Lion” and Shang Hao – rap in English, Mandarin and the Shanghainese dialect.

Their success was triggered by Lionel placing a demo on the web – which eventually led to the pair being picked up by multinational record label EMI. Subsequently the duo had their first hit, Number One.
