connect the two separate album covers. The first album, Mezmerize, was released on May 17, 2005, to favorable reviews by critics. It debuted at No. 1 in the United States, Canada, Australia and all around the world, making it System of A Down's second No. 1 album. First-week sales exceeded 800,000 copies worldwide. The lead single "B.Y.O.B.," which questions the integrity of military recruiting in America, worked its way up the Billboard Modern Rock and Mainstream Rock charts, and would go on to win the 2006 Grammy Award for Best Hard Rock Performance. "Question!" was released as the next single, with Shavo Odadjian co-directing the music video. Following the album's release, the band toured extensively throughout the United States and Canada with The Mars Volta and Bad Acid Trip supporting. The second part of the double album, Hypnotize, was released on November 22, 2005. Like Mezmerize, it debuted at No. 1 in the U.S., making System of a Down, along with The Beatles, rappers 2Pac and DMX, the only artists ever to have two studio albums debut at No. 1 in the same year. "Hypnotize" was released as the lead single and was followed by "Lonely Day" and "Vicinity of Obscenity," all three of which were also released as EPs, including several B-sides from 1999–2000, such as a collaboration with the Wu-Tang Clan, titled "Shame." "Kill Rock 'N Roll" was released as the final promotional single. Whereas on System of a Down's previous albums, most of the lyrics were written and sung by Tankian and the music was co-written by Tankian and Malakian (and sometimes Odadjian), much of the music and lyrics on Mezmerize/Hypnotize were written by Malakian, who also took on a much more dominant role as vocalist on both albums, often leaving Tankian providing keyboards and backing vocals. System of a Down's song "Lonely Day" was nominated for Best Hard Rock Performance in the 49th Grammy Awards in 2007 but lost to "Woman" by Wolfmother. A biography of the band entitled System of a Down: Right Here in Hollywood, written by Ben Myers, was published in May 2006, later being published in the U.S. in 2007 through The Disinformation Company. Additionally in 2006, concert footage and interviews with the band concerning the importance of helping create awareness and recognition of the Armenian genocide were featured in the film Screamers, directed by Carla Garapedian.
