Adrian Sherwood has been around for a long time. He's the man behind the On-U Sound label, and eponymous sound system. The one that usually does the rounds at least once a year, and has done so for as long as you can remember. If you've ever been to an On-U gig you'll know it's loud, uncompromising, live dub sound, and you'd remember there's lots and lots of noise, as you recall the ringing that's left in your ears for hours after.
