Although there are millions of bands in the music scene, not all of them last.
The music scene is supported by kids who go to local music shows and support the local bands. Without the kids, and sometimes adults, who support local music, the music scene will go to the dust.
The local music scene is like a local buisness, all local bands needs money to survive and they need kids to listen to them.
Every band in the music scene has talent, some more than others of course, but many local bands have the potential to get big, no matter what genre.
Music scenes involve having shows where you go out and support loca music by buying merch and having fun while listening to music that you like. you can get personal and meet the bands personally, and most of everyone is friendly at shows. you can meet other great people and spread the word about bands.
All in all, local music is under rated and really needs to be listened too, you'll never know what you'll find.
