Austin Robert Carlile (born September 27, 1987) is an American former musician and current baseball coach from Pensacola, Florida. He is the former lead vocalist of Attack Attack! and Of Mice & Men. After leaving Of Mice & Men, he went to coach youth baseball in Costa Rica. Austin played sports in high school but eventually due to having to require multiple surgeries from Marfan syndrome as a teenager he turned to music as an interest. In late 2016, Carlile departed from Of Mice & Men due to Marfan Syndrome and is currently residing in Guanacaste, Costa Rica.
Carlile formed Attack Attack! (originally called Ambiance) around 2006 when Johnny Franck, Andrew Whiting, Nick White, and Andrew Wetzel met Carlile while playing in local high school bands. In 2008, halfway through a tour supporting Maylene and the Sons of Disaster, Carlile was replaced by Nick Barham, brother of Sleeping With Sirens drummer Gabe Barham Carlile said it was for "personal reasons" that he left the band.
