Joshua Kosker

Joshua Kosker (born March 24, 1980) is best known as a musician, playing guitar and providing backing vocals for The Juliana Theory. A native of Latrobe, Pennsylvania, Joshua was influenced by music when he and grade school friend Stanley Stepanic, a known local noise musician, decided to vent pre-teen angst through maniacal ravings under the title War. Ill-fated War was a noise-rock combination of keyboards and various percussion instruments producing such wonderful tracks as "Goat's Blood" and "Banana Toast", which involved combinations of overdriven, badly tuned guitar riffs, keyboard noise, and offbeat drumming. The band released two cassette tapes before calling it quits and moving on to other projects. Joshua and other high school friends then went on to form the band Dawson High before he left to join The Juliana Theory.

As well as being a talented vocalist and musician, Joshua also produces fine art ranging from 3D sculpture to acrylic landscapes. He is currently developing a company, Soapbox Originals, through which he produces clever T-shirt designs springing from his humorous imagination.

As of late 2008 Joshua has joined his former bandmates Joshua Fiedler and Chad Alan Monticue taking over lead vocal duties for the band Vesta. Vesta has planned a nationwide tour for 2013.
