Last year, when Ninth Avenue West became La Rumba, the club shifted its focus from swing to salsa, a move that reduced the number of wing tip wearers in the crowd while upping its quotient of Latin-music lovers. Now the club is sometimes known as Trinity, a progressive dance environment that has welcomed glow-stick-carrying denizens, international acts like the Basement Jaxx and also spinning sessions from the fabulous Freakbeat DJ duo. Sound like an identity crisis? Nah. It's a smart use of a great space. Let's get ready to Rumba.
