Aw, c'mon now

 Sometimes you hear things which just totally blow you away. Here's a case in point. 

On this absolute banger, The New Pornographers are not just going into math-rock, they've emerged out the other side, into some rarified atmosphere where normal humans can't comprehend what they've just done.

"The Jessica Numbers" has always confused me, as I tried to work out that time-signature. Was it 13/8, or something? No, it's more complex than that. It's a series of guitar hits, which assume the formulation of a reverse Fibonacci series. Thus, each hit is the sum of the FOLLOWING TWO HITS.

The standard series would be: 1,2,3,5 etc, but this is in reverse - so the guitar hits are played as 5, then next time round it's 3, then 2, then 1........

 Aaaaaargh! Basically, it's (I think) an attempt to weld the Golden Ratio into music. My mind isn't just blown, it's scattered to the winds.
