But I thought the whole point of music is that it’s beyond specific conceptions.
I’m not so sure that’s universally true. It was a Romantic notion, but recently music and visual have been closely associated in many ways. In addition to the whole video direction of popular music slideshows are becoming common in classical music performances. James Westwater, who has created numerous slide shows for symphony orchestras, refers to what he is doing as a new art, rather than simply two arts together. Whatever the aesthetics behind it, which needs further investigation, the practice of music in our time indicates that there is a strong symbiotic relationship between the visual and the aural, which may actucally involve reconsideration of the definition of music itself.
