Rio clubland's newest addition ON11 opened with a fanfare in November 2010 and Gui Borrato heading up the proceedings. Thus, with house music lovers' interest piqued the likes of European house heads CircoLoco were signed up to keep the crowds happy and one of the men behind Ibiza's DC10 is charged with the programming. Certainly not cheap, the place isn't pitching itself at (or anywhere near) the underground dance music buff, but with a killer sound and light system you won't find many on the dancefloor who care about that.
