The site is actually a former quarry site. It is a famous place for film & video location in Tochigi Pref., 100km away from Tokyo. http://www.oya909.co.jp/
I’m sorry but I can only hear “en??tsu o ire”. If SU-METAL actually said “enpitsu o ire”, it means “putting a pencil (= comment) on (some text)”, and I can think of no other likely phrase.
Just pretending but they may look as if they were really playing the guitars, because MOAMETAL has taken guitar lessons for several years and knows roughly which fingering (and pose) corresponds to which phrase.
“Tyuurippu” (= tulip) is a famous children’s song published in 1932.
“Hyuu” is uttered, instead of whistling, to make fun of someone(s) (“hiyakasu” in Japanese) when a boy and a girl behave intimately in classroom, when a boy speaks like a hero (and it’s not suitable for the situation), etc.
“Piro piro” means the quick passages (of high notes) played by (heavy metal) guitarists. It is a jargon among heavy metal fans in Japan. MOAMETAL refers to the tapping (one of the guitar techniques) with this word. It’s a cynical word because used by those who think such phrases are self-satisfactory (and less emotional).
