The music within this album, now known as the band's final swansong, holds so much of what has come to define ONE TAIL, ONE HEAD, until now chiefly showcased in its many live incarnations, ranging from the rabid, unruly primitivism of the early material to the ominous, slightly surreal atmospheres they began to explore later on. There is material here as old as a decade, as well as what would be considered brand new, written these past few years. More punk than most punk bands, blacker than most black metal bands, and without being any of the above, "Worlds Open, Worlds Collide" is in its purest form an attempt at organizing absolute chaos: From the doomy opening riff in "Arrival, Yet Again" to the borderline progressive and oddly epic "Summon Surreal Surrender" the strange, wildfire-lit universe of ONE TAIL, ONE HEAD is explored throughout the album.
