Are there any apps/playlists like Spotify's discover weekly

which includes bands that are playing near you in the near future?

find myself often missing out on gigs or discovering a band just after theyve played.

Do you know about https://www.songkick.com/?

It links with Spotify to show you gig listings of bands you listen to

yeah , I dont think thats that great for bands you might want to discover though tbh
