2013 has been the year of reunion. First. Destiny's Child. Then, 'N Sync. And now, the cast School of Rock.

The Jack Black film turns ten years old this October and to celebrate, the cast and crew reunited for a screening and Q&A at the Austin Film Festival. Later, at an after party, the band got back together for a performance, and Miranda Cosgrove thankfully documented much of the event on her Instagram account.
