Task: Question Answering
Input (English): Passage: On February 7, 2012, Metallica announced that it would start a new music festival called Orion Music + More, which took place on June 23 and 24, 2012, in Atlantic City. Metallica also confirmed that it would headline the festival on both days and would perform two of its most critically acclaimed albums in their entirety: The Black Album on one night, and Ride the Lightning on the other. In a July 2012 interview with Canadian radio station 99.3 The Fox, Ulrich said Metallica would not release its new album until at least early 2014. In November 2012, Metallica left Warner Bros. Records and launched an independent record label, Blackened Recordings, which will produce the band's future releases. The band has acquired the rights to all of its studio albums, which will be reissued through the new label. Blackened releases will be licensed through Warner subsidiary Rhino Entertainment in North America and internationally through Universal Music. On September 20, 2012, Metallica announced via its official website that a new DVD containing footage of shows it performed in Quebec in 2009 would be released that December; fans would get the chance to vote for two setlists that would appear on the DVD. The film, titled Quebec Magnetic, was released in the U.S. on December 10, 2012.In an interview with Classic Rock on January 8, 2013, Ulrich said regarding the band's upcoming album, "What we're doing now certainly sounds like a continuation [of Death Magnetic]". He also said, "I love Rick [Rubin]. We all love Rick. We're in touch with Rick constantly. We'll see where it goes. It would stun me if the record came out in 2013." Also in 2013, the band starred in a 3D concert film titled Metallica: Through the Never, which was directed by Antal Nimród and was released in IMAX theaters on September 27. In an interview dated July 22, 2013, Ulrich told Ultimate Guitar, "2014 will be all about making a new Metallica record"; he said the album will most likely be released during 2015. Kirk Hammett and Robert Trujillo later confirmed the band's intention to enter the studio. At the second Orion Music + More festival held in Detroit, the band played under the name "Dehaan"—a reference to actor Dane DeHaan, who starred in Metallica: Through the Never. The band performed its debut album Kill 'Em All in its entirety, celebrating the 30th anniversary of its release. On December 8, 2013, the band played a show called "Freeze 'Em All" in Antarctica, becoming the first band to play on all seven continents. The performance was filmed and released as a live album the same month.
