Cool site: archive.org¶
The Internet Archive is one of the neatest sites on the internet. I like them for a variety of reasons. First and foremost is the live music archive, they currently have 44,134 live concerts posted on their website. Completely free to download/stream til your hearts content. Most of the bands I like these days are on there, and they have an extensive Grateful Dead collection.
They also archive lots of other things, including websites, video, and documents. The main page gives you a partial list of all of the things that they are archiving. Really neat stuff.
