Lyric discussion by Coow 

Cover art for When lyrics by Perfume Genius

Originally a poem by Sharon Olds. Reads as:

"I wonder now only when it will happen, when the young mother will hear the noise like somebody's pressure cooker down the block, going off. She'll go out on the yard, holding her small daughter in her arms, and there, above the end of the street, in the air above the line of the tress, she will see it rising, lifting up over the horizon, the upper rim of the gold ball, large as a giant planet starting to lift up over ours. She will stand there in the yard holding her daughter, looking at it rise and grow and blossom and rise, and the child will open her arms to it, it will look so beautiful."

I imagine that's what is being read at the end of the song.
