I knew they had video content, but not music. Awesome. :)

Some think of the Internet Archive as just the Wayback Machine, but we have other great collections.   Our music collection is worth listening to and made some jumps recently:

Our live music collection now has over 100,000 concerts from over 5,000 bands (including an almost complete collection of Grateful Dead concerts)

…

And the first “music video” from 1894-1895 that was found recently, reconstructed painstakingly by the legendary Walter Murch, and then he donated it to the archive.
