As we previously reported, Chicago post-metal quartet Pelican will return on April 10 with the Ataraxia/Taraxis EP. The four-track EP promises a healthy mix of smoky doom, minimalist electronics, ambient soundscape, and acoustic-desert folk. And on lead track "Lathe Biosas," we're definitely getting a taste of that smoky doom through an all-out assault of guitars, bass, and drums. I was personally hoping for more of the desert folk to rear its head on here, but hey, that's what the rest of the EP is for, right? You can stream and download the track below.
