Lenny Kravitz

The erstwhile enfant terrible of retro rocking, still holding the classic rock beacon aloft.Probably best known for his elaborate stage presence and constant sunglasses-wearing, Kravitz has been around in various guises since the early 90s.

He's worked with Madonna, Steve Tyler, Mick Jagger, Vanessa Paradis and Michael Jackson.

In his own right, you'll know him from singles 'Are You Gonna Go My Way' and 'Fly Away', as well as brief appearances in Precious and The Hunger Games movies.
