Markets in everything

Raves for deaf people:

Aurally frustrated, some deaf hip-hop DJs in East London started setting up their own parties. The kids went mad for it, and soon deaf raves ["Rave" in the UK just means loud DJ party of any sort—Ed.] were drawing hundreds of people from all over the country. I went to one recently at Hackney Ocean and the music was so loud I had to make myself deaf using earplugs.

Inside the club the walls were pulsing to the music but the 500-strong crowd was silent because everybody was just doing excited, drunken sign language. I had no idea what...they were talking about but they were partying way harder than people with ears that work. After years of not being invited to the party, these kids had finally created their own scene and it was exploding.

On stage there was live deaf karaoke where hot deaf girls were frantically signing the lyrics to R&B hits.

Then there was the deaf dance-off, where breakdancers battled to see who was the best at body-popping out of sync to the music.

But the highlight of the night had to be Britain's first deaf rapper, MC Geezer, who signs-rhymes and raps out of time...

Yes, fixed costs are falling.  And thanks to Nacim Bouchtia for the pointer, my apologies if you find the language in the link offensive.
