Imminence Records Sirens has unveiled their boundary pushing new single entitled “Drone” to the world. The single, which can be heard HERE, features technically-driven heavier sections complementing immaculate ambient soundscapes. Drummer/singer Zakk Huff had this to say on the single, “We are excited to present our fans with what we consider to be our heaviest, most demanding, and softest song yet. ‘Drone ’ pushes our boundaries in all directions; intricate rhythmic work, experimental orchestration, distinct vocal lines, dense harmony, massive guitar, and drastic style changes that push the genre “progressive metal” to the limits.”
