Anyone who has ever listened to Gun's N Roses knows that former lead singer Axel Rose had one of the most unique voices in music. He hit notes that nobody else could pull off, such that since the band split up, the lead guitarist Slash couldn't very well perform the music without that unique voice of Axel Rose. That is until he listened to Fergie from the Black Eyed Peas. Axel can't be happy that the person they finally found who could hit his notes and replace him would in fact be a woman.
If you like Gun's N Roses, you have to listen to Fergie doing Paradise City. It is unreal how much she sounds like Axel during the screaming parts.
