I didn't know what Cortis was.

I found out it was a five-member boy group while reading.

The book *Cortis as Seen by Neulkeuk* by Seong Yong-won, a classical music critic and composer distinguished by his sophistication and professional insight, explores the composition, success factors, and exceptional musical world of Cortis—whose motto is "free thinking beyond boundaries"—through its connections with the music of Mahler, Beethoven, Schumann, and Wagner.

It is a boy group I have never heard of before, but it was easy to read.

This book stands out for its intricate analysis of the direction of popular music and, furthermore, the success factors that the stagnant classical music world could envy.

In particular, the immersion, dedication, and activeness of the audience, who make up half of the performance, are aspects that cannot be expected in classical music.

There are so many things to envy that it is too much to simply dismiss them by saying they are in a different field.

As a classical music enthusiast, this is a book that leaves you with even more thoughts and lingering regrets as you close the last page.
