Here is a story I heard:
In the Fifties many touring Jazz bands were playing arrangements of show tunes and local amateur musicians would often bring their instrument to the club and ask to sit in with them. I’m sure the club owners also pressured the bands into letting their paying customers play. Anyway, some of the Jazz bands grew tired of having to let amateurs mess up their music and began developing more and more complex music, with so many chord changes that an amateur would not find his way through the forest of changes… and out of that developement Be-Bop was born.

We are leaving for New Zealand in 5 hours and I haven’t packed anything yet…
