Hailing from Belarus, The Hysteria is appropriately creating some hysteria with their music. They have delivering an experimental Mathcore sound since 2009 and show no signs of slowing their roll.
On the other hand, Nasty Taste is a Math/Metalcore band coming from Russia. They’ve been going strong since 2008. Interestingly enough, they have a female vocalist with beastly talent.
The most recent release for both groups was actually a collaborative effort. They released a split EP a few months back which will likely melt some faces. You can sample bits and pieces down below. And if you enjoy, download the heavy hysteria for FREE on Bandcamp!
