Since reforming earlier this year, Irreversible has been busy. In April the group released the four-song Ashes EP. Now it's put out another pair of EPs, Thorn and Plucked Up By the Root. Where Ashes bridged the distance between the group's aggressive technical/prog metal and spooky atmospheric mien, these EPs split personalities. The former features eight growling metal tire fires. The latter is a 25-minute track of building, cinematic sound, crisscrossed with electronic textures.
