A new re-recording of their debut album, "Luna Sea", was released on March 16, 2011 as a self-cover. In response to the 2011 Tōhoku earthquake and tsunami that occurred on March 11 in Japan, the band released the digital download song "Promise" on April 9. It was their first new song in ten years and was released exclusively on Amazon websites, with all proceeds donated to the Japanese Red Cross to aid the victims. A live album and video of their US concert, both titled "Luna Sea 3D in Los Angeles", was released in June, with the film being shown in Japanese theaters nationwide. On October 22, they held a charity concert titled A Promise to the Brave at Saitama Super Arena, and all proceeds from the event went to the Japanese Red Cross. Tickets for the show went on sale on August 14 and sold out in five minutes.
