Thanks for the history. Of 3,000 CDs, I have Metallica and some more modern metal...that's it.Hi Lloyd guess you are not into rock/metal at all as this is the start.
That is the black Sabbath song by black Sabbath, and that weird tone that repeats, called tritone, is what the anti metal brigade claimed in those was calling the devil. Their guitarist had lost his two fingers while working in a metal factory in Birmingham, and some said that music sounds like heavy metal.
This song and led zep's immigrant song were said to have started heavy metal. Though Plant later said he hoped not because he found metal too structured and samey. The other instance where the term heavy metal was recorded in the early days was when a journalist used the phrase to describe a Jimmy Hendrix concert.
The source for the black Sabbath is tape. For Beethoven 9th is a Garrard and not so good LP
As for the video...the fact that I was particularly intrigued by the quality of the sound...and it was tape...well, that says a lot to me then. I have never heard tape live, and this particularly video certainly makes for an inviting case.
