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.
Tee Nuts are annoying coz there are also T Nuts, which are used in aluminium extrusion channels. And there’s also Tea Nuts which are nuts you put in tea if you are low on iron.
