I started using a service called Concert Archives (it is what it sounds like) and I really like it! It’s helped me remember live shows that I had forgotten I even went to and artists I didn’t even recall seeing until looking at the archive entries.
I wish it was federated with #ActivityPub, something like that on the fediverse would be very cool.
Here’s my profile (still working on adding concerts, lots more to go…) https://www.concertarchives.org/jonathan-rollans
