Lemon Demon is an independant music artist who has a garnered a large Internet fanbase ever since he started the Lemon Demon website in 2003. It's a bit difficult to pin down which genre of music he creates, but it's mainly strange, irreverant, upbeat-with-a-touch-of-dementia pseudo-pop. Since 2003, Lemon Demon has produced and released four albums, titled:

-Clown Circus (April 2003)
-Live from the Haunted Candle Shop (July 2003)
-Hip to the Javabean (March 2004)
-Damn Skippy (March 2005)

His upcoming fifth album, titled "Dinosaurchestra," is slated to be released on July 20, 2006.

His songs have inspired Flash artists to make music videos to some of his songs, including "Geeks In Love" (from Damn Skippy), "The Ultimate Showdown" ("The Ultimate Showdown of Ultimate Destiny;" will be a track on Dinosaurchestra), "Ebaum's World Dot Com" (unsure; currently in "Miscellaneous" section of website), "I've Got Some Falling to Do" (from Hip to the Javabean), and "Hyakugojyuuichi Forever!" ("Hyakugojyuuichi 2003;" from Clown Circus) along with some others not mentioned on his website.

You can order the last two albums from www.lemondemon.com.
Just for clarification, Lemon Demon is a single person: Neil Cicierega, a.k.a. Trapezoid, a.k.a. the creator of Animutation.

Lemon Demon is a band that has a large following, mostly on the internet. They are most famous for the song The Ultimate Showdown of Ultimate Destiny, which is in turn most famous for the popular flash animation that achieved high fame on the website Newgrounds. They are also famous for being pioneers in the anti-eBaum's World movement, by alerting the general public with an informative song, with flash animation to go with it.
I was walking down the street, when I heard some awesome music. I used my ears to see where it was coming from, and walked into the store, which happened to be a music store. I said "man, what's that badass music?". The guy at the music store said "you don't know that band? That's Lemon Demon!".
