Where to find underground /warehouse scene?

Hii everyone <3 I’ve really wanted to go to DJ sets in warehouses and places that are not an official club, but I have no idea how to find them.

I normally listen to a wideee variety of artists, so I’m not even really sure what DJs are good when I see their names on the usual apps for clubs. I just loveee to dance and I really enjoy the music and scene when I go out. Any advice??

Also can someone please clarify if raves are just for techno & EDM or does it also include melodic trance & house kind of music too? I’m trying to learn all of the genres/categories lol I like them all but I feel like I vibe more with the latter.

Thank you so much for your help in advance!!
