The record that launch a thousand garage bands. This and their second album "Paranoid" were required listening if you wanted to play in a rock band when I was a kid. Filled with power chords and riffs, these songs were like the standards everyone needed to know... or at least it seemed that way to 12 year old me. Not my favorite heavy metal records but worthy of giving a listen and studying. I enjoyed listening to this album end to end but it not one I would typically pick for a get together or road trip. You can put it in the archives for future analysis but most likely it won't be included on my mix tape.
