One of the things that separates proper avant-garde art from other art is that "enjoyable" isn't a concern. I recently got to see the avant-garde chef Ferran Adria speak (probably the most important chef of the past 30 years), and one of the key questions he asked was, "Is it my job as a chef to make a meal you will enjoy?" (paraphrased from memory, and he had a translator onstage, so...)
This is a critical question. I used to play avant-garde music myself, in a guitar + drums improvisational duo. It wasn't our job to make music anyone else liked, or even music we liked. We were exploring the limits of sound and the interrelationships of the instruments and ideas. To this day, even in much more mainstream contexts, I play a lot of guitar that doesn't "sound like a guitar". I learned a ton about my instrument, and about sound and music.
