You should listen to the entire song understanding that there are evermore new elements that fill the soundscape. The rythm is similar to dubstep, but there aren’t wobble basses and the trend is peaceful and relaxed. In 2013 Comet ISON was announced to be an important astronomical event. However the things have been different because the comet, turning around the sun, has been destroyed. I made this track in order to use as soundtrack of a time lapse that I didn’t shot, so the title remained the same.
