If you are a jazz lover looking for a test disk for audio components,
let's have a look to :

"Ghosts"
from Celea - Liebman - Reisinger

Dave Liebman play a lot of different instruments.
Jean-Paul Celea's bass sound vary a lot from a track to an other
Wolfgang Reisinger change from simple breath to thunder.

A kind though to all American people in such sad anniversary.

Sincerely,
Lionel
