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!
