Black Sabbath and Zeppelin 3

In the past class we listend to part of Black Sabbath's first album "Black Sabbath" and to part of Led Zeppelin's album "Zeppelin 3". I personally didn't like the Black Sabbath album. I didn't like it because they didnt have great lyrics and I feel like Ozzie didn't have that great of a voice to be singing for as long as he was. I did like "Paranoid" but I had previously listened to it. In "Zeppelin 3" there was a strong influence on acoustic guitars and other instruments of that nature. It sounded odd to me, because it had the same attitude and the singer had the same sound, but it was on acoustic instruments. The songs were decent, but it just didn't sound right to me.
