Using Taxonomy For Classifying Events

Hello My Friends. 

I  hope this finds everyone well, safe and sane.

I'm wondering if anyone is using taxonomy for classifying there events? 

Currently, I use the Type function in event setup when building performances.  I would like to expand the classification further using interest. My goal  to build a robust segmentation engine to use with List Manager when looking to target patrons with similar interests based on their buying behavior.

For Instance:  In the below example the Type = Classical Music.  I then would like use interests to possible tag the event  with 20th Century; Violinist; Soloist. 

If anyone is using taxonomy I'd love to chat with you and if you're not and interested, let's chat too.   I'm looking to discuss all and any genre using classifications for events. 

Thanks.
