Oh yeah? The RIVIERA JAZZ reissue label seems to think differently and seems to have plenty of documentary evidence to prove it. Google it up some time.
I mean that the cultural policy of fascist regime was oriented to rediscover and promote our Roman Empire and Italian Renessaince heritage instead of "negro" music. I know that some good music were played and recorded, Gorni Kramer was the most famous, but, for sure Roma and Milano weren't Paris.
BTW read the pages you suggest
'In 1942 - 1943, while northern Italy was undergoing World War II bombings, although Benito Mussolini had prohibited playing and listening to jazz, some young Italian musicians decided to record "pure" jazz. They recorded, under very difficult conditions, many jazz standards which they gave Italian titles so as to disguise the true origin. The names of the authors were also camouflaged with Italian names. These classics are published on CD for the first time.'
