On their 2018 release ‘Necroshiva’, Kazakhstan’s Zarraza really tightened up their blend of thrash and groove metal. The album, although centring around a couple of tried and tested styles and obvious influences, was incredibly well produced and came loaded with impeccably played riffs. On the best tracks, elements of Lamb of God jostled against bits of Slayer, which resulted in something incredibly powerful, especially when dressed with a dirty hardcore-tinged bottom end. In terms of their abilities with a riff, this underground act were now on a par with French metallers Backdawn, and Atlanta’s Bless The Dead. This tight and mean approach carried the following year’s ‘Rotten Remains’ where the arguably more professional band set about revisiting and re-recording some of their earlier DIY recordings, again with brilliant results.
