Apple's annual WWDC Bash will be headlined this year by rock band Panic! At The Disco. The almost-end-of-WWDC party will take place Thursday evening from 7-10PM at Discovery Meadow, just around the corner from the McEnery Convention Center where the rest of WWDC takes place. The invitation also notes that a "special DJ" will be hosting.
Apple notes that attendees 21 or older may drink alcohol after picking up a wristband on Thursday either on the plaza outside McEnery or at the tent inside Discovery Meadow by showing valid government-issued photo ID. Bag check is not available at the event, Apple notes, "so please leave your bags at the hotel."
The Bash is an annual end-of-WWDC tradition for Apple, though it takes place on Thursday night ahead of the final day, as many attendees fly out on Friday.
