Spring Heeled Jack U.S.A. (more often known simply as Spring Heeled Jack) is a third wave ska band based out of New Haven, Connecticut. The band was formed by guitarist/vocalist Ron Ragona and drummer Dave Karcich in 1991. After a short breakup, Ragona and Karcich reformed the band with a new lineup. This lineup went on to record two albums before announcing a hiatus in 2000. While the band members moved on to perform in several new bands, their intention was to play the occasional reunion show. This plan would never come to fruition as a cerebral aneurysm would be cause for Karcich's death in 2002. In 2013, three members of the band's most well-known lineup reunited the band on a full-time basis.
