Last night was Z100's Jingle Ball, one of lots of holiday megaconcerts held by radio megamarkets this time of year. This one was at Madison Square Garden and had acts like Lady Gaga, Demi Lovato, Kelly Clarkson, LMFAO, David Guetta, and folks like Karmin (the point at which name recognition drops off a tall building.)

The Jingle Ball site has photos of the performances, but pictures don't move and sing things you've heard on the radio yet. So below, here's "Born This Way," "Judas" and "Shots." More to come once more's around.
