See Charli XCX, Jessie J and more at Z100's free All Access Lounge

The glitzy, teen-targeted holiday bash that is Z100's Jingle Ball happens tonight at Madison Square Garden. A few artists you might know—Taylor Swift, Ariana Grande, Maroon 5, Nick Jonas, Sam Smith—will be doing their best to one up each other on the city's biggest stage. Before that though, some of the lineup's smaller but still worthwhile acts—Time Out fave Charli XCX, Jessie J, Kiesza, Rita Ora, Shawn Mendes, Rixton and Meghan Trainor— play Z100 & Coca Cola’s All Access Lounge, happening noon–6pm at the nearby Hammerstein Ballroom. It's free, but you might want to head over soon if you want to get in.

Even if you don't have a ticket to the Jingle Ball, there'll be a stream of the show on Yahoo Live—put it on the TV as you decorate the tree.
