Have you ever heard this statement? Compression isn’t necessary if you want to produce a good mix. Now, this statement may well be true in some instances but when it comes to rock music this is absolutely wrong. Aggressive, full of energy and loud three words that would describe rock music. And if you wish to achieve these things you need compression. The truth of the matter is compression is synonymous with rock music. Now understand that the focal point of any rock music is the vocals, get it wrong and everything else follows down. That is where compression comes in.
