Query: Who mastered this?

Great rocking tunes - musically. There is no digital headroom though with the mix - its pegged to the max. The songs are extremely compressed to the point of distortion even at low volume. It sounds like someone deaf mastered these songs. Even the vocals are distorted. Maybe that's how they wanted it, but this seems to be the growing trend with all digital music - to see how much headroom can be squeezed out of digital levels to the point of low level distortion. Bottom line - the songs rock, but the audiophile in me says they sound like c-r-a-p. It would have sounded better having the band play in a garage and putting up 2 cheap microphones to capture the moment instead of wasting money on a deaf engineer :)
