Bob Dylan has released his first new song in eight years.

The tune – dubbed “Murder Most Foul” – clocks in just below 17 minutes and chronicles the assassination of John F. Kennedy.

“Greetings to my fans and followers with gratitude for all your support and loyalty across the years,” Dylan wrote on the early morning hours of March 27. “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.”
