From today's piping-hot Popbitch missive:

Which hugely cool US rap legend gets his road crew to pull out handsome young men from the audience at his show, and bring them backstage to hang out. If they fail to deliver, one of the road crew has to strip naked and crawl across the dressing room floor and administer oral attention to the sweaty star.

Now the Brits may have a different definition of "rap legend" than you and I, but your hints are:
1) The artist recently has or currently is touring
2) "hugely cool"

"Cool" leads us down the road to the various Ices and K/Cools out there, but damned if we know if any of them are still touring. Weren't they all assigned SAG cards and farmed out to Law & Order spin-offs?

Send your guesses, and they shall be posted.
