When a band you like changes vocalist there are plenty of occasions where it is and obvious upgrade (Bruce Dickinson, Joey Belladonna) or downgrade (Sammy Hagar, Brian Johnson). I was thinking about bands I was into and singers I liked then the band changed singers. Before the album came out my feelings were that it wasn't going to work. They could replace this vocalist, but I was wrong. Either they found someone just as good or it was a slight upgrade. Here are my top choices, feel free to add your own.Metal Church- Mike Howe in for David WayneWayne's voice helped define those first two albums. Howe had a different voice, but just as powerful. It allowed the band to go in slightly different, but just as powerful direction.Helloween- Andi Deris in for Michael KiskeI am sure there are some fans who will totally disagree with me on this one. Kiske helped elevate this band and define power metal in it's early days. Deris was a different style, but they worked the music with his voice and the results are som fine albums over the last 16 years.Dark Angel- Ron Rinehart in for Don DotyI got into this band with Doty and Darkness Descends is still my favorite, but Rinehart brought a heavier direction to the band.Exodus- Steve Souza in for Paul BaloffBonded by blood is still my favorite album and Baloff delivered a fine performance. Souza brought a more controlled performance and allowed the band to go in directions that they may not have able to go with Baloff.Labels: Dark Angel, Exodus, Helloween, Metal Church
