'Caldera' by Raytheon is a pumping tune with dark sounds that take over from the very beginning. But as the song moves into the breakdown, a complete silence takes over, giving way to a synth that is full of tension, in perpetual struggle to rise. The melody in this track comes in from below but is interrupted by the sound of an echoing chorus. This leads to the soaring of the synth - going higher and higher with the drop. This, in turn, brings back the melody that slowly but surely moves towards the final note, putting a sense of harmony in this haunting track.
