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 oldskool music competition at the 2000 Assembly demoparty.[1]
