Sad to hear, though it's of course inevitable that the great Italian composers of a few decades ago can't stay among us eternally ...
Gaslini is one of the Italians whose work I still have to explore more thoroughly, but I already own his score for 'Quando Le Donne Si Chiamavano Madonne', which I definitely enjoy (it's also a great added value that the covers display the ever graceful Edwige Fenech). I'll play this CD today in his memory.
