Various Artists • A New Orleans Jazz Festival • 1949 & 1952 (24/44 Vinyl Rip Mono)

The highlights are tracks 9–11 where you hear not less than 5 Bigbands playing (mostly) simultaneously. The event was called "Gene Norman & Frank Bull Dixieland Jubilee Concert". Later in the 50ies Gene Norman & Frank Bull startet a record label called "Dixieland Jubilee".
When I hear historical recordings like this, I always try to compare them to something in our time. In 1950 Jazz was as old as Techno is today, about 25 years. So for the visitors this event must have been similar to the LoveParades of today.
