I have always been somewhat frightened of powerlines. They are quite beautiful though, and my favorite example of their abstract sense of power is seen in the stellar anime series Serial Experiments Lain.
this and Mister Ambience's "Serial Experiments Lain (1998) Music & Ambience" great for that. especially if your in a hospital dying listening to this, good sh*t would recommend 10/10
Update: I was wrong. I tried visualizing this in Spectroid (a live spectral analysis app for Android, incredibly useful) and it's clearly peaking at 120 Hz.
