Fused in crossover music that bears its dominance through a collection of punk and prescient metal riffs, Cryptic Slaughter (along with D.R.I., C.O.C. and the contributions of punkers like Discharge and The Exploited) built up the genre of thrash music from haphazard crossover to a science of more terrifying, instantaneous music. Deluxe, remastered reissue includes their Life in Grave demo from '85 and a live songs from '88 in Houston.
