Dennis Tapper (18 November 1974 – 15 May 2018), better known by his stage name Hux Flux, was a Swedish solo musician.
Hux Flux was formed in 1998 when Tapper started making music after being influenced by the forest parties outside Örebro in Sweden.
After a few releases on his own, including the hit "Time Slices", Tapper started to work with Jonas Petterson and they produced the album Cryptic Crunch together on the label Koyote Records.
Later, Tapper moved to Stockholm where he started to work with his old friend Henric Fietz.
Tapper also produced tracks such as "Reflux" and "Equivalent Equations" on his own under the name Hux Flux and has also worked on the ambient project Illuminus with Magnus Holte.
