Emil Werstler is an American guitarist and musician based in Atlanta, Georgia, who is perhaps best known for his work with metal and gypsy jazz. In 2004, Werstler became lead guitarist for the metal band Dååth, whose second album The Hinderers peaked at No. 49 on the Top Heatseekers chart in 2007. In 2009 Dååth released The Concealers on Roadrunner, which reached No. 35 on Top Heatseekers and was placed as No. 3 on a list of the "top twenty metal albums of 2009" by Metal Sucks. In 2010 Werstler released the instrumental metal album as a collaboration with Eyal Levi, with the album receiving a largely positive response for its musicianship and experimental nature.
