For the third year in a row, Portland Radio Authority (PRA) is broadcasting all of PDX Pop Now!, the giant, free showcase of what happening in Portland’s pop music scene. Where in the past these broadcasts have been, shall we say, illegal, it’s all legit now, with PRA operating on the intranets (praradio.com), and re-broadcasting on KPSU’s wavelength—98.3 FM. And and and, tablesturned.com will make the recording downloadable, like pronto after the show. So the breakdown is that you have no excuse not to see what PDX Pop Now! sounds like this year. You have your choice of in-the-flesh, on the internet, on the radio, or in your i-pod. So there.
