Filligar is an American rock quartet from Chicago, Illinois. The band was formed in 2000 by brothers Johnny, Teddy and Pete Mathias and their childhood friend Casey Gibson. The lineup has always remained the same. Filligar has written and recorded eight albums and over 80 original songs. The first two albums were recorded in a Chicago basement under the name Flipside, while the quartet was still in their early teens. They invented the name Filligar (based on the Mathias brothers’ sister’s childhood pet) and have since produced five albums recorded at Gravity Studios and Electrical Audio in Chicago.
