Riccardo Muti, in this 2004 video, explains to a bunch of students why the tempest that opens Salieri's L'Europa Riconosciuta is so cool, talks about its similarities to Gluck's Ifigenia in Tauride, jokes about why the late great Antonino Votto's teacher at Conservatorio taught young Antonino (who later became Muti's own teacher) that the score for Guillaume Tell contains everything you need to know about music (and about weather, too).
Muti also speaks a few lines in Neapolitan dialect.
And plays some mean piano.
