Some context: Linkin Park is an American rock band from Agoura Hills, California. Formed in 1996, the band rose to international fame with their debut album Hybrid Theory (2000), which was certified Diamond by the RIAA in 2005 and multi-Platinum in several other countries. Their following studio album Meteora continued the band's success, topping the Billboard 200 album chart in 2003, and was followed by extensive touring and charity work. Having adapted nu metal and rap metal to a radio-friendly yet densely layered style in Hybrid Theory and Meteora, the band explored other genres on their next studio album, Minutes to Midnight (2007).
In July 2011, Bennington told Rolling Stone that Linkin Park aims to produce a new album every eighteen months, and that he would be shocked if a new album did not come out in 2012. He later revealed in another interview in September 2011 that the band was still in the beginning phases of the next album, saying "We just kind of began. We like to keep the creative juices flowing, so we try to keep that going all the time ... we like the direction that we're going in". Later, on March 28, 2012, Shinoda confirmed that the band is filming a music video for "Burn It Down". Joe Hahn directed the video. Shinoda spoke to Co.Create about the album's art, saying that it will "blow them [the fans] away ... the average person is not going to be able to look at it and go, I understand that that's completely new, like not just the image but the way they made the image is totally new. So there's going to be that".  On April 15, 2012, Shinoda announced that Living Things would be the title of Linkin Park's fifth album. Shinoda stated that they chose the title Living Things because the album is more about people, personal interactions, and it is far more personal than their previous albums. The band promoted the album on the 2012 edition of the Honda Civic Tour, with co-headliners Incubus. The band performed "Burn It Down" at 2012 Billboard Music Awards. On May 24, the band released the music video for "Burn It Down" and debuted "Lies Greed Misery", another song from Living Things, on BBC Radio 1. "Powerless", the twelfth and closing track of the album, was featured in the closing credits of the film Abraham Lincoln: Vampire Hunter.  Living Things sold over 223,000 copies during its debut week, ranking No. 1 on the US Albums Charts. Linkin Park's single, "Castle of Glass", was nominated for 'Best Song in a Game' at the 2012 Spike Video Game Awards. The band also performed at the award ceremony on December 7, but lost the award to "Cities" by Beck. Linkin Park also played at the Soundwave music festival in Australia, where they shared the stage with Metallica, Paramore, Slayer and Sum 41.  On August 10, 2013, the band collaborated with American musician Steve Aoki to record the song "A Light That Never Comes" for Linkin Park's online puzzle-action game LP Recharge (short for Linkin Park Recharge), which was launched on Facebook and the official LP Recharge website on September 12, 2013. On the day of the game's release, Linkin Park made a post on their Facebook explaining that the song used to promote the game would be included on a new remix album, entitled Recharged, which was released on October 29, 2013 on CD, vinyl, and digital download. Similar to Reanimation, the album features remixes of ten of the songs from Living Things, with contributions from other artists, such as Ryu of Styles of Beyond, Pusha T, Datsik, KillSonik, Bun B, Money Mark, and Rick Rubin. The band also worked on the soundtrack for the film Mall, which was directed by Joe Hahn.

Some context: "Free as a Bird" is a song originally composed and recorded in 1977 as a home demo by John Lennon. In 1995, a studio version of the recording, incorporating contributions from Paul McCartney, George Harrison and Ringo Starr, was released as a single by the Beatles. It was released 25 years after the break-up of the band and 15 years after the death of Lennon. The single was released as part of the promotion for The Beatles Anthology video documentary and the band's Anthology 1 compilation album.
McCartney, Harrison and Starr originally intended to record some incidental background music, as a trio, for the Anthology project, but later realised, according to Starr, that they wanted to record "new music". According to Harrison, they had always agreed that if one of them was not in the band, the others would never replace them and, "... go out as the Beatles", and that the "only other person that could be in it was John."  McCartney then asked Ono if she had any unreleased recordings by Lennon, so she sent him cassette tapes of four songs. "Free as a Bird" was recorded by Lennon in 1977, in his and Ono's Dakota building apartment in New York City, but was not complete. Lennon introduced the song on the cassette by imitating a New York accent and saying, "Free--as a boid" (bird). The other songs were "Grow Old With Me", "Real Love", and "Now and Then". Ono says that it was Harrison and former Beatles road manager Neil Aspinall who initially asked her about the concept of adding vocals and instrumentation to Lennon's demo tapes. Ono stated: "People have said it was all agreed when Paul came over to New York to induct John into the Rock and Roll Hall of Fame, but it was all settled before then. I just used that occasion to hand over the tapes personally to Paul."  McCartney went to Ono's home after the induction ceremony at the Rock and Roll Hall of Fame to listen to, and receive, the Lennon demo tapes; he recalls the meeting with Ono:  She was there with Sean ... and she played us a couple of tracks. There were two newies on mono cassettes which he did at home ... [s]o I checked it out with Sean, because I didn't want him to have a problem with it. He said, "Well, it'll be weird hearing a dead guy on lead vocal. But give it a try." I said to them both, "If it doesn't work out, you can veto it." When I told George and Ringo I'd agreed to that they were going, "What? What if we love it?" It didn't come to that, luckily. I said to Yoko, "Don't impose too many conditions on us, it's really difficult to do this, spiritually. We don't know, we may hate each other after two hours in the studio and just walk out. So don't put any conditions, it's tough enough."  During an interview for the Anthology project, McCartney revealed that he was surprised to learn that Lennon's demos of "Grow Old With Me" and "Real Love" had already been released and were well known by Lennon fans. Starr admitted that when he first listened to the recording he found it very emotional.
