A Melodic Death/Doom Metal band from Lund, Sweden. They combine the aggressive yet melodic aspects of melo-death(such as the bands In Flames or Dark Tranquility) with some occasional sad tones reminiscent of Doom metal(like Katatonia, Green Carnation, Candlemass, etc.).
"The Hollow Grounds" is a beutiful song you must hear.
Pandemonium is an obscure and extremely talented band.
