One thing that really stands out about System of a Down is their lyrical prowess, and their vocal style. I have yet to find another band that is similiar to SOAD in their vocal style. As to their lyrical prowess, SOAD is a perfect example of an intelligent rock band. They definitely have something to say about the world, and B.Y.O.B. is a good example of that, with lines like "Why don't the presidents fight the war?" and "Why do they always send the poor?". Also, some of their other songs are about drugies and prostitutes, and other things that are wrong with the world today. While most of their stuff is political, not all of it is, but it all has a point to put out into the media. As for the music itself, as musicians they are also pretty technical, which is somewhat rare in bands that focus on ideals in their lyrics. This album is devoid of solos, but it has decent riffs and grooves that fit with the vocals and with the other instruments. Some people dislike the singers' vocals, so it may be an acquired taste. Excellent Album.
+Great Harmony between instruments & vocalists
-Some find the vocals to be annoying
-Somewhat simple instrumental parts
