I just wanted to share something I find very useful. I've always had problems singing other peoples songs BC In a subconscious way try to imitate the Artists voice...the result is always an akward and forced attempt. I came across s few sites for cover Bands and after listening to some of their samples I had the chance to listen to some very accomplished musicians give their own version of Floyd songs. I guess its just refreshing to hear normal folks give it their all. Anyway, the more different versions I listen to, the less I try to sing like Gilmour/Waters and the more I sing like myself, albeit very limited. Anyway here are some of the bands:
