An old school goth is one who listens to goth rock that was recorded and released from 1979-1985 (the prototype goth era) before the goth subculture embraced techno, goth metal and industrial music. These old school goths do not always wair overtly costly clothing like modern goths and are often be found in more everyday clothing. Old school goths will often listen to bands such as bauhaus, The Cure, The Damned, Siouxsie and The Banshees (in other words, post punk and goth rock) as well as various other genres that influenced or are asscosiated with the early goth movement such as dub, reggae, punk rock, glam rock and genres that influenced early goth rock. Most old school goths never listen to goth metal and certainly object to the commercialism of the goth subculture and fashion as seen by mall punks and mall goths whom don't even listen to goth rock.
