There is more than one artist with this name: 1) Depression is a German underground Death/Grind Band.
Website: http://depression-grind.de 2) Depression is a doom/death band from Russia that was formed in 1993. Released the demo "Венок печали" in 1995 and "Распятье Богов" in 1996. Apparently, they recorded two new tracks (presumably live) from 2007-2008, and played a concert in Moscow during this time. Monstrously huge, expansive Doom/Death Metal, with a heavy emphasis on the Doom.
