Their fourth album, Boxer, was released on May 22, 2007, and also received widespread critical praise. The album features contributions from various guest artists, including Sufjan Stevens and Doveman. It was voted as the No. 2 best album of the year by Stereogum.com and the No. 1 album of the year by Paste. The song "Slow Show" from Boxer was featured on the NBC series Chuck and Parenthood, as well as on The CW's One Tree Hill in its fifth season. The song "Start a War" was featured on the international science fiction series Defying Gravity, ABC's Brothers and Sisters, Fox's House, NBC's Parenthood, NBC's Friday Night Lights, Lionsgate film Warrior. The track "Fake Empire" was featured in the Season 2 Premiere of the HBO series Hung and on the third episode of season 2 of NBC's Chuck and in the pilot episode of Southland. An instrumental version of the song was featured in Barack Obama's campaign video "Signs of Hope and Change" during his 2008 United States presidential campaign, and the song was also played at the 2008 Democratic National Convention.  On September 26, 2007, the band performed "Apartment Story" on The Late Late Show with Craig Ferguson.  In the summer of 2008, along with Modest Mouse, they opened for R.E.M. on the promotional tour for the R.E.M. album Accelerate. That summer they played many festivals in North America and Europe, including Coachella, Roskilde, Sasquatch, Glastonbury, Haldern Pop, Rock Werchter, Optimus Alive!, Oxegen, Benicassim, Lowlands, O2 Wireless, T in the Park, All Points West, and Lollapalooza.  Boxer made numerous "album of the decade" lists, including Pitchfork Media, Aquarium Drunkard, Paste, and more. It has sold nearly 430,000 copies in the U.S.  In May 2008, the band released their first feature-length documentary film titled A Skin, a Night on DVD. The film, directed by filmmaker Vincent Moon, documents the lives of the band surrounding the recording of Boxer and just before a show at the London venue Koko. Along with the release of the DVD was a CD collection of B-sides and rarities titled The Virginia EP. The National's collaboration with Vincent Moon began long before the filming of A Skin, a Night. Vincent Moon discovered the band after the release of their first album and became friends with its members after a show at Paris' La Guinguette Pirate. Soon after this meeting, Moon filmed his first music videos ever, which were for the National's songs "Daughters of the Soho Riots" and "Lit Up". Moon's photography also appears on the cover for Alligator. CANNOTANSWER
