As with many releases from the Gdansk, Poland, band that was supposed to appear at Austin’s SXSW, a gentle, urging melody swirls around a lyrical message, laid bare by haunting new video that echoes the band’s theme: radical, dark, anti-hate-speech songs. The lyrics are often only snippets, phrases, designed to provoke rather than soothe, hint rather than resolve. As we can see now how easy it is for a snowman to melt.
