Here's your daily look at 'Today in Rock History' featuring: Lzzy Hale from Halestorm is 36. Dale Earnhardt, Jr. is 45. David Lee Roth is 65.

In 1988, U2 released their "Rattle and Hum" and in 2007, Radiohead released their seventh album "In Rainbows" with that weird "pay-what-you-want" download option.
