Sound — 10
System Of A Down are my all time favourite band, and this is my all time favourite album, the sound is great riffs, amazingly distinctive vocals, and a big innovation in rock music, its very hard but soft vocals back this up to an amazing set of songs, so that itself is a reason to buy it.
Lyrics — 10
The lyrics are mostly not tied down to political songs, such as "Boom" or "Prison Song", and opens up to modern songs, the lyrics having meaning to them rather than senseless screaming and yelling found in most bands and groups, and has genuinely great vocalists, drummer, bassist, and guitarists that make an amazing album.
Overall Impression — 10
The best System album, a perfect example of an album, and in my opinion, flawless, "Toxicity" and "Chop Suey" being the standout songs in this brilliant, album, I'm rating this album 10 out of 10, and its the gold standard, by which all future albums should be judged, that's entertainment all right.
