I actually preferred his voice on the earlier stuff. It was raw, untouched and deeper than it is now. It was especially amazing for someone in their late teens to come out with.
Cool review, I love the album. Jimmy's voice sounds great both ways, but this new sound is refreshing to the ears.
I just meant that the vocals changed significantly and out of necessity (he said that singing like that was hurting his throat). I greatly prefer his party scene voice to any other.
