There’s a pretty bold claim in this 99% Invisible episode: R.E.M.’s Out of Time is the most politically significant album of all time. Before you get your Peter, Paul, and Mary’s in a twist, give the episode a listen. It’s a fascinating history of ’80s and ’90s politics, censorship, and anti-waste activism.

If you aren’t already a fan of the show, consider this the hint of the century and check it out.
