Formulas Fatal To The Flesh - Formulas Fatal to the Flesh is the fifth full-length studio album by death metal band Morbid Angel. The Satanic themed lyrics of previous albums had been replaced with lyrics about the Old Ones, which would become the primary source of Morbid Angel's lyrical content from this point on. This is the first album to feature singer/bassist Steve Tucker, replacing David Vincent, and has some lyrical content written in Sumerian. The tunings for this record as on Covenant and Domination remained E? on six string guitar songs, and B? on seven stringed guitar songs
