Having been involved in making underground music for nigh on thirty years, vocalist Gaahl has amassed a body of work ranging from high voltage Black Metal with Gorgoroth and the less polished Trelldom, to the traditional folk stylings of Wardruna, ramping up his progressive blackened leanings with God Seed, before releasing GastiR – Ghosts Invited (Indie Recordings), the debut offering of current vehicle Gaahls Wyrd, in 2019.
