I did something a similar except instead of music I'm a huge theme park fan and wanted a portion of my personal site to be dedicated to my trips (instead of hosting the pictures on Facebook or the like) so I decided to separate out the roller coaster portion of my persona and put it at a subdomain of my personal site (https://coasters.joshimbriani.com for those curious) whereas my main site remains mostly tech focused (https://joshimbriani.com). I've been pretty pleased with the setup for now seeing as how I can nerd out about coasters without alienating the other half of my (non-existent) audience
