Kurt Cobain and Amy Winehouse impersonators

I was watching to random videos over Youtube last night, when I've ran into two amazing impersonators of Kurt Cobain and Amy Winehouse.

It appears to be a peruvian TV show called Yo Soy (which means I am, in English) where the contestants pretend to be music celebrities.

To succeed they have not only look to like them but also to sing like them. These two impersonations have really surprised me... but there are a few details that should be improved, like their accent in some words for example.

If you know about more people who impersonate music celebrities please leave me a comment with a video link!
