Bob Dylan has continued to release his first original music in eight years, with a song in which he seemingly compares himself to Anne Frank, Indiana Jones, the Rolling Stones and William Blake.

At four and a half minutes, I Contain Multitudes is less lengthy than the song he returned with, Murder Most Foul, a 17-minute long track about the JFK assassination. Like that song, though, I Contain Multitudes is drifting and percussion-free, backed by acoustic, electric and pedal steel guitars.

The 78-year-old songwriter announced it with a hashtag-strewn tweet: "#today and #tomorrow, #skeletons and #nudes, #sparkle and #flash, #AnneFrank and #IndianaJones, #fastcars and #fastfood, #bluejeans and #queens, #Beethoven and #Chopin, #life and #death."
