Janne Suni

Janne "Tempest" Suni is a Finnish demoscener, pixel artist and tracker musician, and a member of the demogroup Fairlight. 
He is best known outside the demoscene for being the creator of the song "Acidjazzed Evening", the melody of which hip-hop producer Timbaland plagiarized in the 2006 song "Do It" by Nelly Furtado (see Timbaland plagiarism controversy).
"Acidjazzed Evening" originally won the oldschool music competition at the 2000 Assembly demoparty.
