Blabbermouth.net states "The first class recording team... ...harnesses the unit's musical ferocity, emphasizing every detail, right down to vocalist terrorist John Pettibone's paint-peeling delivery. It is in fact an all-consuming sound with an emphasis on the splitting of ears. The shock of the up tick in fury occurring after the first spin is downright destabilizing."[1]
Jason Jordan on the Last Rites website states the album "is a good, thrashy metalcore record that surpasses the band's previous entries, but not by a considerable distance", that "Summon in Thunder is noticeably heavier and more memorable than any disc in their catalog", and "it's also a testament to the fact that this quintet is improving while moving up the metal ladder simultaneously."[2]
