System of a Down is out with new music for the first time in 15 years. Why now? Members of the heavy metal group, who are of Armenian descent, said the current conflict between Armenia and Azerbaijan brought them together. Proceeds from “Protect The Land” and “Genocidal Humanoidz” will go to the Armenian Fund, assisting with humanitarian efforts in the region. The tracks can be purchased at Bandcamp.

“The time to do this is now, as together, the four of us have something extremely important to say as a unified voice,” members of the band — Serj Tankian, Daron Malakian, Shavo Odadjian and John Dolmayan — said on Instagram. “These two songs, ‘Protect The Land’ and ‘Genocidal Humanoidz’ both speak of a dire and serious war being perpetrated upon our cultural homelands of Artsakh and Armenia.”
