1. Happy birthday, Jimi Hendrix! The guitarist would have turned 70 today.

    From the All Things Considered archives, hear the story behind “Purple Haze,” with thoughts by original Jimi Hendrix Experience engineer Eddie Kramer and this quotable nugget from Living Colour guitarist Vernon Reid: “He was unabashedly sexual. He didn’t apologize to black people for being wild, and he didn’t apologize — he certainly didn’t ask for permission from white people. He laid down a gauntlet, you know, he said, ‘Are you prepared to be free?’”
