Hypnotize, the companion CD to Mesmerize, completes a double album of the best music that System of a Down has ever created. This second half offers stranger and at times much more discordant tunes than Mesmerize. That is what is so good about it though. Hypnotize’s themes are a little bit darker than Mesmerize’s so the music is naturally darker. Many of the tracks are reminiscent of the older tracks of the original album. The sound, however, has evolved immensely with extremely complex guitar riffs, multiple layers of sound and amazing vocal harmony. The accompanying lyrics are also outstanding. You may find yourself headbanging and shedding tears in the same song. It’s hard to describe everything that makes this album so awesome. If you like any of System of a Down’s previous CD’s, then you should buy Hypnotize…NOW!
