First of all, I want to tell the poster:
1. "Cats" is not an opera, it is a musical. It is essentially the same genre as the current "High School Musical", except for the composition. The techniques are different.
2. "Cats" is modern. Its author is Andrew Webber, the ex-husband of Sarah Brightman (the woman who sang You and Me at the Beijing Olympics).
3. The female singing voice in "Cats" is not considered bel canto, it is just a popular singing style combined with a little bel canto singing technique.
Then let me answer the poster’s question:
If you like memory, then you probably like Weber’s composition style, so you can listen to all his works. I highly recommend "Phantom of the Opera". This movie was made into a movie in 2004. There are a lot of handsome guys and beauties. You can feast your eyes while enjoying the music~~haha~~~
Well, you can go Download (you can also watch it directly on the video website) Andrew Webb's 50th birthday concert, which is full of superstars. There are classic tracks from all his works. Go and listen to it. If you think it sounds good, just watch the corresponding full concert. Drama.
In addition to Weber, I would also recommend some French musicals to you, such as "Romeo and Juliet" and "Notre Dame de Paris". Although they are in French and are all recorded live, the compositions are The singing and singing are both top-notch. You can just download the original soundtrack.
Finally, I recommend you to listen to a real classical opera. You must have heard many of the arias before, such as Haba Nie La in Bizet's "Carmen".
If you still have any questions, just ask, or send me a direct message on the site. I am very happy to help you, because when it comes to this aspect, it is my interest and expertise~haha~~ ~~
