The best way to find new music, imo, is going to shows. People tend to skip openers and they are missing out. Sometimes they suck. Sometimes they don’t. Either way it’s a band you probably wouldn’t have seen otherwise.

I went to see cherry glazerr on a whim and discovered vagabon who was from new York, and shannon lay who is from here in LA. I liked both more than the main act. 

Take chances. Hit up different sized venues. 

Don’t look for a specific sound, just try to find something that has potential to lead you into more your zone. Death metal and britpop probably don’t mix too often but if you can find a good shoegaze band, you might hit some of their shows and find something you really like. 

The other options are bandcamp, spotify, and YouTube. Just spend some time going down the rabbit hole. Make playlists of what is interesting, and listen to those a lot. It’ll start recommending things based on those listens.

I recommend checking out college radio station online streams in the genres you like. Also, chatting with the DJs could really expand your knowledge, too (most of them LOVE to talk music with listeners).
