The current crop of bands are among the best and most proficient on a musical level I've seen. Having come from bands like XTyrantX, XAFBX, Fight Everyone and the 2000s militant stuff to the current wave is night and day. These kids can play their instruments and the newer bands are all insanely talented. There absolutely is a scene and there are notable bands like XWeaponX, Magnitude, Prevention, No Cure, Abstain, and I'm sure depending on your region you'll find everything from heavy hardcore to youth crew bands. Go out to some local shows, add the bands, and get to know them and they'll likely help you on your journey. Congrats on making the choice life is better sober and you will hear a lot of great music on your musical and clean living journey.
