In 2005 Faroese songwriter Hans Marius Ziska formed his group, then only titled Marius. Since the formation of the group, Heðin has been a regular guitarist and collaborator as the group has developed from a rock group, to a songwriting outfit, with room for different styles and sounds.
The band Yggdrasil formed in 1984. Having been a regular guitarist for Kristian Blak, Yggdrasils band leader, it was quite natrual for Heðin to join the band in 2002.
Multitalented artist Herikkur á Heygum has been making music since early 2000.
Heðin started working with Heiðrik á Heygum in 2005 and is now regularily performing with Heiðrik.
