Why not? It gives me great satisfaction to be able to convince people to explore or re-evaluate a composer's music which I admire.
But, ultimately, the person has to want
to explore or re-evaluate the composer's music. No amount of convincing would have ever made me give Schnittke's music another try, but there was always this lingering doubt in my mind that I'm missing something. The same applied to Holmboe for me. You can go back through my posts and you will find someone who wasn't very thrilled with Holmboe's music, but I continued to be persistent about his music because I knew there was something great about it. So people have to decide for themselves and make up their own minds in the end.
