Songkick? I’ve been using it for a few years and it works reasonably well. I believe you can connect it to Spotify too. The only negative is it’s usually 3-5 days behind the announcement of shows. Following the artist directly is still the best bet to guarantee you hear it straight away. But that’s only a problem if the show/artist is super popular and sells out fast.
Generally I try to have a creative, hands-on project on the go. Lately that’s been rebuilding a guitar, but it could be designing something on the computer.
Otherwise; playing guitar, gardening, practice putting (disc golf). So I guess hobbies.
