Zur Erinnerung: Am 24. Juni bringen Porcupine Tree ihr Comebackalbum "Closure/Continuation" via Music For Nations/Sony heraus; mit "Harridan" und "On The New Day" wurden bereits zwei Stücke vorgestellt, nun folgt mit "Herd Culling" der dritte Song. Allerdings zunächst nur in gekürzter Single-Fassung, die komplette Version dazu wird auf dem Album enthalten sein, wie den Worten von Fronter Steven Wilson zu entnehmen ist:
"It was the final song written for the album. When the rest of the songs were assembled we felt there was still musically a 'hole' for something dramatic in the middle of the album, so it became the only song written as a three way collaboration between all of us. Beginning with Gavin coming up with an unusual rhythm in 11 (he’ll never give you something easy!), it was then a case of myself and Richard finding the music, and both of us working with sequenced electronics and sound design, alongside the quiet/loud guitar dynamics. The full 7 minute version is a musical storytelling which features several other sections, but I think the edit works quite well as a more conventionally structured piece too - a smaller bite of music. Lyrically it’s about a very specific event in history, but it also deals with the broader theme of paranoia in the modern age - someone or something is coming up your driveway or in your front garden, and their/its motives are unclear. The title obviously takes on extra resonance in our Covid times."
