After the success of the Guitar Hero video game series; Activision is branching out, and a launch party was held on June 1st for its DJ Hero video game which is all set to hit the shelves later this year.

Eminem and Jay-Z closed the party in supreme style with their incredible MC ability, and such stars were in attendance as Leonardo DiCaprio, Ali Larter, Vanessa Minnillo, and even rock stars Mark Hoppus and Pete Wentz.

Travis Barker and DJ AM opened the show with their mixing, and Warren G was also there to please the crowds with his DJ skills. It was only right that the DJ Hero launch party should include such a fantastic selection of talented DJ stars, with DJ AM actually one of the DJs to have provided original mixes for DJ Hero, along with DJ Shadow, DJ Z-Trip, and Daft Punk.

Despite the quality bill of DJ talent; the best was most definitely saved till last at the DJ Hero launch party, and it was almost midnight by the time that Jay-Z and Eminem took to the stage to wow the celebrity masses.

Jay-Z was up first, and launched through a set which included such tracks as ’99 Problems’, ‘Encore’, ‘H To The Izzo’, and ‘My President is Black’, before combining forces with Eminem for ‘Renegade’. Eminem then bounced through a few tracks of his own from his new ‘Relapse’ album, closing the set with ‘Lose Yourself’ and well and truly getting the LA crowd on their feet.

It was a very successful night of entertainment for the launch of the new video game, and Activision was able to show off its new DJ Hero video game, complete with a fantastic line-up of talented musicians to lighten the mood and make sure that all in attendance enjoyed their evening.
