“BTW, do you have the CD’s which match modern accompaniment with scrubbed versions of Caruso singing?”
No I don’t, in fact I didn’t know they existed. I’m going to look for the CD’s now though, because I’d love to have them. I’ll bet I can find them on Amazon, unless you have a better idea (I shop on the Internet mostly nowadays).
The first are the operatic arias (includes his "Recitar!...vesti la giubba" from I Pagliacci), the later Italian popular songs (includes the usual suspects). Gottfried Rabl conducting the Vienna Radio Symphony Orchestra for the modern accompaniments. A little over two hours you will enjoy.
