Bay Area progressive death metallers Anisoptera are set to release their full-length debut, Spawn of Odonata, next Friday, September 14. Brimming with bludgeoning groove and dizzying complexity, Anisoptera‘s forthcoming album will satisfy fans of Decrepit Birth, Spawn of Possession, and those who just like their death metal overwhelmingly heavy. In anticipation of its release, we at Svbterranean bring you a stream of their new single, “Ammonite”. Though it is one of the band’s oldest tracks, it was given a brutal facelift for the upcoming LP. If you’re looking to get smashed to pieces, look no further.
