The Agonist is a Canadian metal band from Montreal, Quebec, formed in 2004. The current line up consists of guitarists Danny Marino and Pascal (Paco) Jobin, bassist Chris Kells, drummer Simon Mckay, and vocalist Vicky Psarakis, who joined in March 2014 following the departure of vocalist and founding member Alissa White-Gluz (who now fronts Arch Enemy). Both Psarakis and White-Gluz use growled and clean vocals. Originally known as The Tempest, the band adopted their current moniker upon their signing to Century Media in 2007.
