The year 1965 is regarded as one of the best for rock music.

Bob Dylan released "Mr. Tambourine Man," Smokey Robinson and the Miracles had a hit with "The Tracks of My Tears." And The Rolling Stones wrote their smash "Satisfaction" at a hotel pool in Clearwater, Florida.

But for one writer, 1965 wasn't just a great year for music - it was a groundbreaking year.

We talk to Andrew Grant Jackson, his new book  is called, "1965: The Most Revolutionary Year in Music."
