Oplen is the electronic music project by swedish music producer Henrik Sunbring. The idea of Oplen is to make music by using electronic equipment and effects outside the computer, just record and mix into the  computer.

The aim is to create  an individual idiosyncratic sound by creating own samples. The music is  inluenced by techno, post rock and 70"s  music. "flyttstress" was recorded and mixed under improvisation in kalamarelabbet august 2005. Henrik is also a member of the post rock agent music band Kalamare Beat Club.
