On Dec. 3, in conjunction with SiriusXM’s Phish Radio and Pandora, Phish will perform at The Met in Philadelphia.

And since the 3,500-seat room is one of the smallest venues Phish has played in some time, tickets are in high demand.

If you haven’t gotten your hands on a pair of tickets yet, don’t worry. SiriusXM is giving away 20 pairs of tickets for the intimate performance.

The drawing for a winner will happen “on or around Nov. 19” and tickets are non-transferrable.
