Great album and great band. The review on the other hand can use some work. The singer's name is Brian Nagan. I would not consider Kevin to be a lead vocalist when he was in the band. And Brian is not the replacement singer since he has been the band's singer since the band began.
But I do agree that Key to the World is a standout track. It is by far my favorite off the album.
Appreciate the corrections, I got a bit of contradicting information on who was lead/backup when I was writing this and just went with my best guess.
Hopefully the changes I made regarding the lineup make the review more accurate :)
