Technically not the most representative track of the genre, but exceedingly listenable and you get some idea of what the rough vocals that are normally in blackgaze sound like. If you like the contrast, then blackgaze is definitely for you. If you prefer clean vocals, there are bands such as Astronoid That only have clean vocals.
Overall, blackgaze is the intersection between black metal which has heavy/fast drums and screamed vocals, With Shoegaze, which is a warm tone, lots of effects, my bloody valentine being the most recognizable example.
