The music video for "Embedded" was directed by Grammy Award nominated Popcore films. The album received generally positive reviews, with Kerrang! magazine saying, "an album that quite literally obliterates everyone else currently residing within the death and grind scenes" and "one of the year's most essential metal purchases". Scott Alisoglu of Blabbermouth.net, praised the album saying that Genesis "is a strong modern death metal release". Those who pre-ordered the album received signed copies in the days preceding its official release date of May 15, 2007. Genesis is the final release by Job for a Cowboy to feature founding member Ravi Bhadriraju. This album also marked the last time the band would work with drummer Elliot Sellers, who announced that he would be leaving the band immediately after recording to go back to school. He was replaced by Jon Rice for the following tour and remains with the band to this day. Genesis is a concept album in which mentions the VeriChip, a radio-frequency identification (RFID) microchip, that is supposed to be implanted under the human skin. The device has generated controversy among certain religious groups, which have become against the possible use of it, as there is a Biblical prophecy where all persons must receive the Mark of the Beast "on their right hand or on their foreheads", described in Book of Revelation 13: 16–18, to participate in economic activity under the government of the Antichrist. Chad Bowar of About.com described the band's musical evolution, saying: "Job for a Cowboy's sound has evolved from deathcore to straight ahead death metal." Bowar also praised the guitarists Ravi Bhadriraju and Bobby Thompson, saying that both have done a "good job at creating innovative riffs and play some quick but skillfull solos."
