Pacha: Mark Knight and D. Ramirez

The big club is bringing in two major-league jocks for the price of one, as Mark Knight—the U.K. house veteran and Toolroom Records label master with a sound that ranges from smooth and deep to tough and jacking—joins fellow Brit club-music lifer, Slave Recordings' D. Ramirez, in the booth. Go to the club's website to get on the reduced-admission list.
