Gregory John “Greg” Puciato (born March 27, 1980) is the lead singer of the band The Dillinger Escape Plan, The Black Queen, 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 Dillinger Escape Plan 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, Puciato started out as a fan of the band in their earlier days. When the band split with their singer Dimitri Minakakis (due to him wanting to focus more on Graphic Arts/Design), they searched publicly for a new singer by releasing the instrumental version of the song “43% Burnt” (off of their debut album). 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. Coincidentally, the band’s first release with Puciato was for a Black Flag tribute compilation, where they covered Damaged I and II.

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”.

Greg’s debut album Child Soldier: Creator of God is due for release in 2020.
