Iron To Gold, Desperate Times, Outbound and Last Dayz, and also a number of labels making sure these bands are released on tape & vinyl. Reality Check plays heavy up-tempo hardcore akin to bands like Terror, No Turning Back and such. Good stuff. They contacted me (and other blogs) about putting their 2011 demo up for download. Since doing this demo they appeared on the excellent 'Very Cool & Very Core' compilation 7" from 2012 which showcases 6 bands from the current Polish hardcore scene, including some of the aforementioned bands, as well doing a 7" called 'The World On My Shoulders' in late 2012. The compilation 7" was released on Poland's own Ratel Records, and the EP was released on 2 other Polish labels, Elephant Skin Records and Last Warning Records. So if you want a taste of the current Polish hardcore scene, check out Reality Check and the other bands, and the labels. There's some pretty good stuff coming out of Poland, so give it a chance.
