‘Ticket to Ride’ – The Beatles
According to Lennon, this was the first heavy metal song ever written. For example, McCartney performed lead guitar. “On the fade-out, we practically invented the idea of a new bit of a song,” he said of “Ticket.” “At the time, it was pretty innovative.”

‘Whipping Post’ – The Allman Brothers Band
This anthem was written by Allman on an ironing board in a dark Florida bedroom. The song is best appreciated in its 23-minute version on At Fillmore East, which is punctuated by knifelike guitar incisions from Duane Allman.
