The thing with the 70's is that reggae became very popular with the white 'rock' crowd, it had already done big things in Jamaica for its own crowd, but when Marley and others got into the American and UK audiences it just lifted. You cannot repeat this, all that has happened since is the continuation of these things in a more modern style. The latter part of the question answers this. As a lover of reggae music I fail to see how anyone can't take in the messages that are presented, as an individual I try and live a good life and try to be good to my fellow man. Too many people want some kind of power over another and I see this in religion as well, so I don't adhere to any religious order.
Life is an inspiration.
Your web site is an excellent resource and I've seen a number of posts from you on the rec.music.reggae newsgroup. I thought I'd try the Internet after being shown it by John from Alpha and Omega. As with most forms of music, reggae has its different styles and it's usual that those that like one don't always like the other, a roots man may not like ragga etc. Anyway things have progressed a little now for reggae on the net, but I don't think it's revolutionised anything. For me the e-mail thing has been useful, making contacts all over the world, which has helped me get shows and helped the music get a little wider airplay, I think it's still progressing.
