   Before digital delays and reverb, there were analogue devices.  Some of the 
   expensive studio reverbs were called "plate" reverbs.  They were big sheets of 
   metal, usually built into a wall or something for isolation that the sound was 
   run through.  Cheaper versions of this were "spring" reverbs, which consists of 
   a box with a few springs running through it.  If you pick up an old guitar amp 
   with spring reverb, turn it on and then drop it a little bit, you'll hear a big 
   reverberated crash.  It's the springs bouncing around inside the reverb case.

The sound of somebody whacking a spring reverb can be heard in the last
section of Rael (the part that later became Sparks).  Try doing that with a
digital reverb!
