I was just searching for some old-school (seventies) tunes to listen to at work, and came across a few bluesy tracks by Earth, the quartet composed of Ozzy Osbourne, Tony Iommi, Geezer Butler, and Bill Ward before they renamed themselves Black Sabbath and conquered the world with heavy metal.
Looks like the music was posted today by a YouTuber known as "Thebestdream I had". Sounds pretty interesting.
And for all you Judas Priest fans, there's also a few tracks featuring Glenn Tipton's previous group, Flying Hat Band.
Rock on people!
