the last two CD's of system of a down

Mezmerize and hypnotize are two different CD's. Even though mezmerize come out before they come in pack of two. The father of the guitarist (Daron Malakian) is Vartan Malakian and he drew the cover of the both albums. The Grammy Award-winning 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. The next single, "Question" was released with Shavo Odadjian co-directing the music video.Following the release of Mezmerize, the band toured extensively throughout the United States and Canada .
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 Serj Tankian (the lead singer) and Daron Malakian(The guitarist) (and sometimes Shavo Odadjian[the bassman]) much of the music and lyrics on Mezmerize/Hypnotize were written by Daron Malakian who also took on a much more dominant role as vocalist on both albums, often leaving Serj Tankian providing keyboards and backing vocals.
