This is one of the finest death metal cds in my collection. It is probably the epitome of Gorguts sound and song writing. The songs here are not as easy to get into as the debut album but the songs on Erosion of Sanity are more rich; filled with more odd tempo changes and time signatures, psychotic riffs and precision blast beat drumming. If you like albums like "legion" by Deicide you will love this.
