This rocking celebration revels in Star Wars nerdery. Six of the city’s top groups will do battle on stage in full Star Wars regalia, playing everything from surf to hip hop to metal. The Psyders, Blue Magpie and members of Round Eye will take part, while DJ BO spins Star Wars themed insanity. Dress up for a chance to win the Prize for Best Costume. Rumor has it that the reclusive Yoda will make an appearance. For more Shanghai tunes, check out our Sounds of Shanghai series. Listen to Round Eye on Bandcamp.
