The Crying Tree of Mercury

"The Crying Tree of Mercury" (working title "Slow Song") is a song from The Smashing Pumpkins' fifth studio album, Machina/The Machines of God. An early version of the song called "The Mercury Tree" appeared in early premaster releases of Machina, though it had identical lyrical content. Before joining the Pumpkins, former drummer Mike Byrne played in a band called The Mercury Tree, though it is unclear if this is mere coincidence.

Music video
An internet-only interactive music video was released for "The Crying Tree of Mercury" by MTV in March 2000, directed by Billy Corgan. Machina artwork designer Vasily Kafanov worked with MTV designers to create the video. It was essentially a small Flash animation with clickable Machina imagery.
