The Glasspack is an American psychedelic punk rock band from Louisville, Kentucky, United States. The band was formed in 1999 by frontman and native Louisvillian "Dirty" Dave Johnson, in hopes of giving a better alternative to the classic and hard rock played over-and-over on the radio. The Glasspack has since recorded one garage EP, two garage albums, two studio albums, and numerous cover songs, as well as toured the U.S. relentlessly. Three of the LPs were released on Detroit's Small Stone Records. The band takes its name from the high-flow fiber-glass filled automobile muffler known as a glasspack, which are known for being louder than traditional mufflers.
