FOX News Radio's Chris Foster reports:

("Take Five")

Dave Brubeck was a day shy of 92 years old. He died of heart failure on the way to a cardiologist appointment, according to his manager.

The Dave Brubek Quartet's "Time Out" from 1959 was the first jazz album to sell a million copies. And he was the first modern jazz musician on the cover of 'TIME Magazine'.

("Blue Rondo a la Turk")

He served as a musician during World War II, when his "Wolf Pack Band" was the only integrated unit in the military.

Besides jazz, he composed music for opera, ballet, a Charlie Brown TV special, and a contemporary mass. Sometimes, joined by some of his six children.
