Marco Kalnenek [*1969] is a musician and internet entrepreneur from Heerlen, the Netherlands. Marco initially released music under the nom-de-plume Weirdomusic, a name which was first used for his 1992 cassette release "Someweirdomusic". It is now the name of his website Weirdomusic.com and various related musical activities.

Marco started playing the piano at age 9. His first band Foolish Behaviour was formed around 1982, when he started jamming and recording tapes with his pal Marco Dörenberg and assorted other friends. Hundreds of hours of music and other noises were recorded in the 12 years that followed. A few cassettes and cd-r's were privately released and a couple of tracks turned up on compilations made by other people. Most of the home recordings from 1982-1994 still survive in Marco's cassette archive. These will hopefully be transferred to digital formats in the not too distant future.

In 1994 Marco's interest in writing and recording music started to fade, mainly due to his bad experiences at the Conservatory of Music in Maastricht, where he studied jazz piano for 6 years between 1987 and 1993. No new music was created and Marco started writing for various magazines and, since 1998, internet sites.

In 2001 two older recordings were remixed by Dutch musician Ton Rückert and Japanese dj Hideo Nakai for an as yet unreleased cd-compilation of Weirdomusic's work. Meanwhile Marco began experimenting with pc based composing and recording. His first new recording in nearly 10 years was released on a Comfort Stand Recordings compilation in april 2004, but there was still no sign of a full-blown creative rebirth, and only a handful of tracks were made public between 2004 and 2008.

The end of 2008 saw a couple of changes in Marco's private life, which finally led to the decision to make the new year a special one: 2009 will be the year of Marco's return to the world of arts!
