MilkmanDan says... I tend to agree. However, In-A-Gadda-Da-Vida and Born to Be Wild are really close to tipping the scale in my head from "hard rock" to "metal". The cover of Summertime Blues mentioned in the video, not so much (at least to my ear). Anyway, it is cool to see/hear some of the early influences that got things going in the direction of the music that I love, even if none of them jump out and make me say "now THAT is metal" like Sabbath. Mordhaus said: 1970, Sabbath. That is all.
