I think it's the underlying theme. Velvet is soft. Buzzsaw is a tool used to cut through pretty hard materials. Good artists focus on creating good art, no matter which industry. The film shows us how people who represent artists and the ones creating the market aren't actually artists. In fact, many a time, they don't even know what they are doing.
- Morf is a critic who uses circumstances to make his decision on the
artwork.
- Rhodora will do anything to increase the price of the art she owns.
- Jon Dondon is a complete art-noob.
- Gretchen too will do anything to increase the price of the art she
owns.
These people aren't artists in the movie, yet are market makers.
The tool they have to influence the sell of an artist is a soft skill - reviews, personal relationship, networking, etc. But the effect of that is deadly (much like a buzzsaw) to the art and the artist.
One bad review sends Ricky into a coma. Or a 4 million deal on Hoboman is cancelled and is made to collect dust.
