When are a staple in the Norwegian avant-garde electronic alterno-psych scene, if there even is such a thing. When is the work of Lars Pedersen and a number of miscellaneous collaborators. The band's beginnings date back as far as 1987 with the Drowning But Learning album. Eleven more albums have since been released. As the '90s drew to a close, When enjoyed a bit of attention due to the endorsements of several Norwegian black metal bands who were themselves heading in a more experimental direction. In fact, the Psychedelic Wunderbaum album (1998) was released through Garm of Ulver's label, Jester. This is my favorite When album and a great introduction to this band. When is hard to describe. The best I can do is to call it psychedelic pop breakbeat acid weirdness. So infectious and bubbly, yet a chord of uneasiness permeates the entire work. In 1999 Psychedelic Wunderbaum didn't leave my discman for weeks. It was absolutely habit forming. Let's see if it has the same affect on you.
