Error in reasoning Post Hardcore is perhaps another variant of Hardcore punk because it cames from Hardcore punk But if Lacuna Coil was a Gothic METAL band they can not be a Post Gothic ROCK band because they never played Gothic ROCK Thus they re a Post Gothic METAL band That s a big stylistical difference Lacuna Coil s music shows no roots in Post Punk music the true origin of Gothic Rock Their music is a simple variant of Alternative Heavy Metal Rock
