Cameron Carpenter, an excentric organist
Without doubt, an outstanding virtuoso and a very talented musician.

His renditions of Chopin's études on the organ are extraordinary. Listen to this first: https://www.youtube.com/watch?v=Tn8cZTKLLxA&t=34   until about 3:30.

He plays the "revolutionary" étude in the pedal register. I couldn't believe what I was hearing - had to see the pedal work on the video... https://www.youtube.com/watch?v=wr9SXtvunwk

A refreshingly unorthodox performance of Dupré's Prelude and Fugue op. 7 no. 1 (1920)

An arrangement of part II of Scriabin's 4th sonata: https://www.youtube.com/watch?v=UWSXRWs8I84

The vulgarity of his latest promotional video has incited numerous people to post parodies of that video on Youtube. A good parody is this: https://www.youtube.com/watch?v=HgKKxs7Xf8k  (All video is unchanged from the promo clip.)
