It just doesn’t resonate with me at all. I consider it “strange” because it appears to be lacking any of the emotions I have experienced in my 40+ years. Even more “strange” that it is considered the finest form of musical expression.
Once there was this group of Vietnamese musicians playing on the Mall in Washington DC. It was part of an international festival. It reminded me of cats caterwauling. Overtones that set your teeth on edge. Strange half tones and quarter tones. Nasal singing.
It was really strange at first, but after a while I came to appreciate it. I could start to see where they were coming from. I went to their tent and they let me play their instruments, which was a lot of fun.
Black Dice, a noise band. They are strange because they use dissonance, disrythmia, and other techniques to subvert the usual concept of what music can be, and what they create is music because they wind different types of patterns, both subtle and blatant, through their songs, and because what they make is beautiful.
I was going to say Frank Zappa playing a bicycle , or some of the exotic Phillip Glass things, but instead I will go with The Sex Pistols, who are the most untalented and overrated of all music.
I came across the music of Toru Takemitsu recently. The composer says this: “My music is like a garden, and I am the gardener. Listening to my music can be compared with walking through a garden and experiencing the changes in light, pattern and texture.” His music sounds harsh and discordant and yet I feel there is a beauty there that always eludes me.
