Technically dub is reggae mixed to have vocals removed or toned down.
Officially both forms of music make me unreasonably angry at the world. Really. Unreasonably angry. There's just nothing I can do about it.
So if you see me and my mood changes suddenly, have a listen. There could be dub or reggae playing somewhere nearby. Just get me out of there and get me in a '100%' immersion bath immediately.
