This week we talk with rock guitarist Joe Perry of Aerosmith about his new autobiography "Rocks: My Life in and out of Aerosmith".

Rocks is an unusually searching memoir of a life that spans from the top of the world to the bottom of the barrel—several times. It is a study of endurance and brotherhood, with Perry providing remarkable candor about Tyler, as well as new insights into their powerful but troubled relationship. It is an insider’s portrait of the rock and roll family, featuring everyone from Jimmy Page to Alice Cooper, Bette Midler to Chuck Berry, John Belushi to Al Hirschfeld.
