I'm a huge fan of the genres (even though one has to keep quiet of such fandoms in certain circles) and been to plenty of shows for each.
Some of my favorites have been Link80

Also listen to a good amount of NOFX, Voodoo Glow Skulls, Catch-22, Goldfinger, Waffle Stompers, Streetlight Manifesto, Save Ferris, Adicts, Varukers, so many more that I cannot think of atm.
