"Tetragrammatical Astygmata" is the third (fifth, counting live records) full-length studio release from the Austin-based black metal band Averse Sefira. It was the last of their albums to be released on an independent metal label; in 2006, the band would jump to Candlelight and release their label debut in 2008. Much like that disc, this is split into categories; tracks 1-3 are "Blood", tracks 4 & 5 are "Flesh", tracks 6 & 7 are "Death", and tracks 8-10 are "Earth".
