Jens Arnsted (more commonly known as Yenz Leonhardt or Yenz Cheyenne) is a heavy metal musician, born July 4 1961 in Vordingborg, Denmark.
He has performed as a vocalist, guitarist and bassist throughout his career, and has focused more on the latter in recent times.
Jens joined Brats in 1979 as bass player and vocalist (he was in fact the predecessor of King Diamond), and also performed in the short-lived band Geisha as Yenz Cheyenne.
In more recent years, Jens has featured prominently in the German Power Metal scene, collaborating often with Piet Sielck. He played in Iron Savior, Savage Circus, Stormwarrior, and is the touring bass player for Lacrimosa. Jens also played rhythm guitar for the progressive rock band Kingdom Come.
