Krakow’s Unsound Festival has unveiled its theme for the 2015 event: Surprise. A press release dispatched earlier today contained only scans of two heavily redacted pages on Unsound letterhead. The “confirmed artist” page (pictured above) is entirely blacked out, while another sheet with festival details (pictured below) has very little legible content, but asks one key question: “How do our expectations affect the value we place on music as an art form?” Unsound isn’t the first festival to wager its ticket sales against a strong reputation by keeping its line-up under wraps: earlier this year, partner festival Les Siestes Electroniques, in France, did the same.

Unsound takes place this year between October 11 and 18, and ticket sales open at noon on June 10.
