Max Richter

Composer Max Richter's new album drew inspiration from the Universal Declaration of Human Rights, a document spearheaded by Eleanor Roosevelt which he calls "a blueprint for a better world."

If counting sheep isn't working, British composer Max Richter's latest piece might. Sleep is eight hours long and designed to help listeners get some shut-eye.

The composer has done a brave thing for any artist in any medium: He's messed with a classic, specifically, Vivaldi's most famous four violin concertos. Richter says he had "to figure out how much Max and how much Vivaldi there was going on at every moment."
