The legal risk these days is pretty minimal, copyright is a diseased institution, the savings are substantial*... As rational as any other suggestion I know of.
* I have 1851 tracks currently; this would cost, at a minimum, thousands to acquire legally, and worse for me, because so many of them are Japanese doujin music, I would have to pay major premiums for international shipping or simple rarity of the physical release.
At the risk of sounding like a sappy old grandmother, I really enjoyed Faces of America and the current follow-up series Finding Your Roots. You can watch them for free on PBS. They're both done by Henry Louis Gates (the Harvard professor that famously got arrested entering his own house).*
The show features extensive research into the genealogies of a whichever celebrities are on that episode. We learn interesting details about their ancestors but it's much more about the historical context in which those ancestors lived. Once the paper trail runs out (for some it's a few generations, for others a 1000+ years) the show turns to genetics.
A few cool things so far:
*Funny story: the officer that arrested him said that Gates told him "yo mama." He really said he was coming back from a recording with Yo-Yo Ma (who was featured in Faces of America).
Razib Khan has some criticism of that show (a consultant for 23andme who worked with Gates for the show shows up in the comments).
This is the monthly thread for posting media of various types that you've found that you enjoy. I find that reading the sequences makes me less likely to enjoy some entertainment media that is otherwise quite popular, and finding media recommended by LWers is a good way to mitigate this. Post what you're reading, listening to, watching, and your opinion of it. Post recommendations to blogs. Post whatever media you feel like discussing! To see previous recommendations, check out the older threads.
