Cover art for Nightcall lyrics by London Grammar

It’s not “Night Call”, it’s “NightCall” (call associated with dread), is about toying with one's emotions, to invoke extreme lust. Don’t look towards the literal meaning of the words, instead pay attention to how they make you feel, it's essence, invocation of desire, through fear and anticipation of it.

It's an ingenious song, truly a master stroke ;)
