Error in reasoning PostHardcore is perhaps another variant of Hardcore punk because it cames from Hardcore punk But if Lacuna Coil was a Gothic METAL band they cannot be a PostGothic ROCK band because they never played Gothic ROCK Thus theyre a PostGothicMETAL band Thats a big stylistical difference Lacuna Coils music shows no roots in PostPunk music the true origin of Gothic Rock Their music is a simple variant of Alternative Heavy Metal Rock
