I would like to recommend the Медуза podcasts to advanced learners of Russian.
You can find them on iTunes and on Подкасты — Meduza. There are no transcripts for those, but the sound quality is excellent.
In short, this is what wikipedia says about Meduza:
"Meduza is run by a team of around 20 journalists who resigned from their jobs at Lenta.ru following Galina Timchenko’s unexpected removal from her post by the website’s owner and Vladimir Putin ally, the oligarch Alexander Mamut. There are no Latvian journalists in the project. Timchenko told Forbes that the decision to base Meduza in Latvia was made since “right now, establishing an independent Russian language publishing house in Latvia is possible, while in Russia it is not.”
