Recommend me some unusual and unique metal

Mr. Bungle (the self-titled album. The rest don't really qualify as "metal".)
Kayo Dot
Maudlin of the Well


There are a lot more, but I can't think of them off of the top of my head.
 
"Lämmer am Hanger" by Excelsis

As far as I've heard Excelsis fuckin' rule, but all I've ever been able to hear was the song We Are Kings and their stuff on myspace. Are their albums any good? I've seriously considered buying them but I'm too uncertain.

For the OP, try:

Virgin Black (albums: Sombre Romantic and Elegant... and Dying; they're symphonic goth metal with some extreme influences)
 
Deathspell Omega
The Axis of Perdition
Unexpect
Fantamos
Meshuggah
Obsidian
Coprofago
Spiral Architect
Alarum
Diabolical Masquerade
Genphis Tron
Indricothere
Twisted Into Form
Zero Hour
 
Theory In Practice. Like a more brutal Atheist with a lesser show offy Yngwie Malmsteen on guitar and atmospheric synths,very rare and very very good. Becomes extremely addictive after a wile.
 
Portal (very original, but they are terrible)
Bethlehem (dark, chilling blackened doom)
Molested (weird old school dm)
Svest (weird French bm)
Masters Hammer (especially The Jelmince Occultist, though Ritual is far better)
 
Portal is fantastic!
