I was late to liking opera, twenty something years ago. My cds of Verdi are not whole operas but compilations of singers doing various bits.
I'll put one on now. The rigoletto goes for 34 minutes, approx.
I was also...but once I got the bug, it was huge.
If you have Pavarotti doing the tenor's arias from Rigoletto...they are gems. The final quartet is one of my favorite pieces of music from opera. The cast on PBS was second-class at best...and that particular piece went over like a lead life jacket.
Hey...they tried...and did much better than I would have, but I sing like a New York Taxi does.
