Blackoutt is instrumental stoner/grunge rock band from Slovenia. With uncompromising riffs and psychedelic guitars, they immerse themselves in raw instrumentals, not caring about the absence of vocals. You can find a lot of punk rock and grunge noise influences from the 90's in Blackoutt which makes their music ambiental and flowing, yet heavy at the same time.
These Slovenian riff masters have some of the best riffage for buck. Stoner with Grunge influence just means these fuckers get high and drink some good rot gut before laying down the riffs. This shit will make a real womans panties wet and send the weak into a masturbatory self-flagellation. By "Old Man Doom"
