It's been almost a month since local electro-pop trio Certainly, Sir played the Enormous Room. Attendees of the venue had a chance to pick up their newest album, Tan, which is oddly only sold in Japan. Tan includes guest vocals from Ben Gibbard of Death Cab for Cutie/ The Postal Service, and some really fresh synth beats The new disc will be available – along with another Cambridge appearance of the group tomorrow night at the Middle East Downstairs. Bostonist has hooked up a guest list spot for you and a friend if you're the lucky winner of the Certainly, Sir contest. Email us at bostonist.contest at gmail dot com with the subject Certainly, Sir and let us know you'd like to enter. We'll print out all the entries, scatter them on our floor and randomly select the winner at noon tomorrow. Get in quick – this contest gets you into the show and a copy of Tan, and you don't even have to go to Japan.
