Last night, Activision hosted a rooftop listening party at New York City's Gramercy Park Hotel, for the soundtrack to its upcoming 'DJ Hero 2' video game. The sequel to 2009's 'Guitar Hero' spin-off features mixes of songs like Eminem's 'Not Afraid,' Lady Gaga's 'Just Dance' and Lil Wayne's 'Lollipop.'

Tastemakers, music critics and artists including Tek of Smif-N-Wessun, DJ Evil Dee of Black Moon and DJ J. Period, who also DJ'd at the event, listened to cuts from the soundtrack. In the new version of DJ Hero microphones have been incorporated with its turntable controller and will be available in a special party bundle. Stations with XBox 360s were set up around the venue, giving attendees the opportunity to try out 'DJ Hero 2,' which features playable characters like RZA and Dave Guetta.

'DJ Hero 2' is due in stores October 19. For more information and to play the DJ Hero "Name That Mix" challenge, visit DJHero.com.
