Started with Stretch, Purple and Rush in the 70s. Added in folk and world music in the 80s.
Returned to metal after the dark ages via Arch Enemy, Agalloch, a band formerly known as Isis, To-Mera and Negura Bunget all split or changed.
Got to thank bandcamp for Oskar Schuster, Veela and Michelle Gurevich.
A shame there's no k-pop on Bandcamp.
