Hoppy Kamiyama (ホッピー 神山, Hoppī Kamiyama, born 1960) is a Japanese keyboardist and music producer who has worked with artists such as eX-Girl, The Pugs, Bradford Reed, Bill Laswell, Jan Linton, Marc Ribot, Hugh Hopper/Elton Dean and Damo Suzuki.
[1][2] His record company, God Mountain, was named after the English translation of his family name.
[3] God Mountain was established in 1993 after his frustration with EMI pulling two of his albums from sale.
[4] Kamiyama cites Mauricio Kagel, Luciano Berio, Iannis Xenakis and Karlheinz Stockhausen as his influences – artists with a "bizarre sense and distorted feel and touch".
[5] His nickname is derived from Hoppy, a cheap Japanese liquor that he drank during his early professional musician days.
