The new 3-disc release of the 1927 film _The Jazz Singer_ (just released today) includes a 10+ minute short titled "Bernardo De Pace: the 'Wizard of the Mandolin'," which is on disc 3 of the set. This is an old Vitaphone recording which was one of the first synchronized film and sound techniques.
I'd never heard of de Pace but he's an extremely accomplished mandolinist. The video is in two parts: the first half screens him in full-shot; the second half is filmed at a medium shot, so you can get a better view of his technique. Most of what he plays are Italian classical pieces, with some novelty tunes mixed in, and the final selection is all speed--it gives Emory Lester's "William Tell Overture" a run for its money.
The sad thing in this performance is that he's dressed in a clown costume, and has a plastered down wig. He also mugs a lot for the camera. It's a shame that someone with this much talent had to be packaged in what I take to be a degrading way.
If you can get over this, I recommend it.
I did a quick websearch and found an item about his grandson. At the end of that article in the Minneapolis Star-Tribune, he talks about his grandfather having played command performances for royalty. I hope he was able to do this without the clown get up.
