North Ireland indie rock trio Two Door Cinema Club is gearing up to release the full-length followup to its 2010 debut Tourist History. Today, the band unveiled a free download of “Sleep Alone,” the first single from Beacon and a song they been playing on tour since they were on the Euro festival circuit last fall. The download comes courtesy of the band’s US label, Glassnote Records, and will be available for 24 hours only – so grab yourself an mp3 at the band’s website. Two Door Cinema Club are on tour this summer and fall, and will be swinging by Philadelphia on September 29 for a performance at The Electric Factory. Tickets to that all-ages show go onsale tomorrow, and range from $26.50 to $36.50. Beacon will be available in the U.S. on Sept. 4.
