"To those critics I would say you haven't listened to enough grime music because there's so many creative people in the scene for someone to belittle us with that statement," Rage, 32, a member of the Slew Dem Crew, told Reuters.
"Grime is now being accepted all over the world. We are seeing people of all races and genders actively listening to, buying and making grime music."

The grime artists do tackle drugs, money, respect, turf wars and other gritty topics, all set over a tempo of 140 beats per minute.
"A lot of us come from dark backgrounds and deeper struggles so the real lyrics we write may have violence in them but it's just a form of expression," said Clipson, another member of the Slew Dem Crew.
