The song, The Wolf is Loose, by Mastodon, obviously references the Heroic Journey within its lyrics:

The hero of the gods
The crossing of the threshold
The belly of the whale
Refusal of return
Hollow eyes
Dry pale legs
Howling on
Thru fields and graves
Language of the signs
Symbols to our sight
Guardian to thy throne
Take on form
Daylight
Hide the skin
Cut it off
Scatter ash in the wind
Shapeshifter rolling on winds of tyrants make
Fierce lore of fanged horn
Danger all the way
Night's sea reflection
The faces of bodies slain
Returning to the form of natural human's fate
Grown from the cold
Spirits unclean
Dealer of the days
The ice will thaw
As the soldier walks thru the crimson side
Researchers of aftermath
Dispelling disarming man
One-toed horses subject of Genesis
And the immigrants
Fundamental side of a human mind
Hulder folk and fairies
So believe
The hero of the gods
The crossing of the threshold
The belly of the whale
Refusal of return (1)

The first four and last four lines of the song represent steps of the journey ("Hero of the Gods" could be interpreted as either the Master of Two Worlds, or, alternately, "Supernatural Aid" if seen as "The Gods' Hero".). The song itself seems to talk of a warring yet split hero who undertakes a perilous journey, but sees the horrors of it afterward.
