Bob Dylan released a new 17-minute song titled “Murder Most Foul” to surprised fans, which he said they “might find interesting.” The track explores 60 years of American popular history and is framed around the assassination of President John F. Kennedy in 1963.

“Greetings to my fans and followers with gratitude for all your support and loyalty across the years,” Dylan said in a brief statement. “This is an unreleased song we recorded a while back that you might find interesting. Stay safe, stay observant and may God be with you.”

It’s been eight years since Dylan last released new music on the 2012 album Tempest. During the past decade, he recorded three records of songs originally written in the first half of the 20th century: 2015's Shadows in the Night, 2016's Fallen Angels and 2017's triple-LP Triplicate.
