Pterygium is another discovery that was brought to a bigger audience via the 'Projekt Neue Ordnung II' 4LP Box. The Australian outfit did surprise with his outstanding atmospheric droned textured power electronics. 'Concealing The Past', Pterygium's first CD and second full length album compiles a assemblage of studio recordings from 2017 and 2018. From jarring analogue live sessions to melancholic, nonchalant atmospheres, each piece disconnects from the next, self containing singularity ideas that present as individual representations of every day chaos and detachment.
