There's something about drum'n'bass that makes it sit perfectly alongside the usual musical offerings at rock festivals. It could have something to do with the crashing drums and ear-splitting bass that are reminiscent of high-volume rock bands, or the presence of a live MC that adds immediacy to the sound. Whatever it is, drum'n'bass followers will again be well catered for at Rockit, with appearances by two of the genre's leading lights, Goldie and Adam F. In the past, many electronic music fans complained that other genres such as house and trance were being ignored at Rockit in favour of drum'n'bass. But come night-time many of these same people could be seen at the front of the marquee jumping around to the sounds of overseas DJs such as Marky, Die and Krust. There's bound to be lots of frenetic jumping when Goldie hits the decks, as the British DJ/producer has learned how to work a crowd since emerging at the birth of drum'n' bass. The DJ born Clifford Price became the movement's first superstar with his 90s chart hit Inner City Life, and with his chunky jewellery and gold-capped teeth became the face of the urban movement. Coming out of a troubled childhood, Goldie immersed himself in hip hop culture as a teenager and became an accomplished breakdancer and graffiti artist. In the early 1990s, he was introduced to the breakbeat culture that evolved into drum 'n'bass and founded the genre's first big imprint, Metalheadz. The label was responsible for releasing influential records by drum'n'bass artists such as Optical, Photek and Peshay, and his own debut album, Timeless - one of the genre's landmark releases. Goldie is a disciple of the dark side of drum'n'bass, and his brutal, heavy style could shock those expecting jazz-flavoured offerings like those dropped by Marky last year. Approaching the sound from a different angle is Adam F, who, as the son of 70s glam rocker Alvin Stardust, has lived a life surrounded by music. Born Adam Fenton, the DJ/producer has worked with stars including Missy Elliot, Redman and LL Cool J. If the marquee sound system can cope with the punishment, the Goldie and Adam F shows should go down in Hong Kong drum'n'bass history.
