Hidden in Alice in Chains' classic album 'Dirt' lies 'Intro (Dream Sequence) / Iron Gland.' The song went unlisted on the 1992 release of Alice in Chains' sophomore album and was tucked between 'God Smack' and 'Hate to Feel,' which caused the track listing to become inaccurate.

The bizarre track pays homage to Black Sabbath's 'Iron Man' as well as the classic horror film 'The Shining.'
