Icelandic singer Bjork has likened her experience of working with Timbaland to "dancing the tango". The superproducer worked with the star on 2007 LP Volta, and Bjork insists the experience was full of surprises - and similar to the fast-paced steps of the well-known dance. She says, "He's very macho - in the nicest way possible. He has a very primitive and productive energy. It me feel like a tango dancer being thrown around. But despite Timbaland's machismo, Bjork vowed to retain a degree of femininity in the music they were making together. She adds, "I wanted a bit more embroidery in it, because I'm a chick."
