P/O Massacre's second album 'Aural Corrosion' features collaborations with Alex Buess and Merzbow. The music relies on signal chain manipulation and features clanging post-punk chords, ultra-sludgy doom riffs, and echoing tones like signals sent through clouds of poison gas. The CD and digital versions feature a bonus track 'Nonslaught', created by Ponomarev and Obrazeena alone. The collaboration with Buess is the more conventionally musical, albeit abrasive, of the two. Pre-order is open and the official release date is March 3.
