One of the great things about YouTube is that you can discover a lot of great music from the 60s and 70s that was not very popular back when it came out, and as they say, if you’ve never heard it, it’s new.
You discover great music from the twenties and thirties too.
And then bands like Postmodern Jukebox show that music of today would be much better if performed by better musicians and rescored for other instruments.
