Classic disco grooves get a hip-hop update as the seven top crews must add some 70s moves to their street dance routines.The crew that performed first was Blueprint Cru who won ABDC's first immunity last week. Then Saltare, Poreotix, and Hype 5-0 was all safe from getting the most votes. Leaving Heavy Impact, Static Noyze, and Jungle Boogie in the Bottom 3 to battle it out. Heavy Impact got boot at the auditions and Static Noyze's Beethoven was alittle bit too staticy (dont you just love how i try to be funny, but i just ends up corny? lol), so they both eliminated. Next week is the Usher Challenge. Only on MTV, new on thursdays at 10PM/9C.
