The members all have had various side projects. Anders Brixen Kristiansen was in Nobody Beats The Beats and released a solo album as Track 72 in 2005. In 2007 he was in the band Booty Cologne. Bukki Blæs was in Bikstok Røgsystem and in 2007 he formed the band Balstyrko. After their 2004 pause the three members of Malk De Koijn have performed in various theatrical productions in various combinations.
A longtime reunion rumour proved right when the band appeared at the 2009 Roskilde Festival, playing several new songs and teasing for a new album that would eventually be released in 2011 going straight to #1 in the danish album chart. Bukki Blæs's Balstyrko released their debut album in 2009 and also performed at the 2009 Roskilde Festival.
