Some Korn.
Blind
This is from about 25 - 30 seconds in, with a bass string pluck in the middle of the graph and I don't understand... it's showing a lot of activity in the 20hz and infrasonic range, but I'm not feeling/hearing anything and the subs aren't moving at all. It's like that for the whole first 30 seconds or more.

Here's a graph with some more bass drops a little later in the song. The infrasonic activity shown on the chart just stops short, as you can see to the left.
