This is a genre that is fairly obscure and hard to get into. Some bands label themselves as 'RIO' but as far as I'm concerned, 'RIO' (Rock In Opposition) was just a movement during the 70s, opposing record labels as they refused to sign up bands due to their nature. There is no defined sound here and could vary from band to band. I suppose modern acts are still influenced by the movement, and hence, the only reason it's still floating around. But the true meaning of it is no longer relevant.
Anyway, for some of you wackos, this thread might be of interest

. The above picture outlines some of the essential bands. Other than those, there are quite a few others worth noting as well, although the genre is limited a bit. Lets see how this turns out anyways. I'll update this after a day or so, and if any of you do have anything to add, then go ahead. Till then, for starters, some of you could try the Samla Mammas Manna album I upped a while back (the link still works). They're one of the more accessible bands.
