Gregory John Puciato is the lead singer of the band The Dillinger Escape Plan and the supergroup Killer Be Killed. He is known for his reckless live performances, wide vocal range, and outspoken views, having caused controversy due to both performances and interviews. He joined the group in September 2001 and first performed with the group weeks later at the CMJ music conference in October 2001. In a scenario mirroring that of young Henry Rollins & Black Flag, and Mark "Barney" Greenway & Napalm Death, Puciato started out as a fan of the band in their earlier days. When the band split with their singer Dimitri Minakakis, they searched publicly for a new singer by releasing the instrumental version of the song "43% Burnt". Puciato sent in a tape with one version of him mimicking Dimitri Minakakis and one with his own take on the song. He was contacted shortly after by the band, auditioned in person, and was subsequently asked to join. In the December 2007 issue of Revolver Puciato was voted one of the "37 greatest metal frontmen" of all time. In 2013 he was named number one by MetalSucks in their listing of "top 25 modern metal frontmen".
