Check out this Vietnamese based female-fronted metalcore band called Windrunner. The song Marionette comes off their upcoming full length entitled VUI which will be released later this month. The song also features the vocalist of In Vice Versa.
The female vocals really packs a lot of emotion in them…the way it should be. Her clean vocals are amazing and I would actually love to hear songs with just clean vocals and see how big this band could get! The music itself crosses treads close to that metalcore / emotional hardcore line in the sane…hence the emotional vibe in the music and lyrics.
