Click on SIC Radical and then chose the right date.
The festival will be broadcasted in TV and the schedule matches the festival running order (http://rockinriolisboa.sapo.pt/en/cartaz/).
I think we will get a broadcast and since the last few years always had a stream I think we will get a stream as well.
"Instrumental only" or "No vocals" or something like that should also be added.
