Touché!!! But in general I'm more
It's alright to break the rules you know. With Soundgarden and Nirvana I had the feeling they didn't even know them. Maybe it's my Yuropean background - all that classical music that has left an imprint even though I don't listen too classical music much at all. Unless weird harmonies are done well, they bug me. A lot of Led Zep bugged me in that way, very often I found them harmonically neither here nor there (probably their blues background) whereas with Purple they never left you doubting whether what they played was in major or minor. You hear a track like Burn,
you know that riff is in a minor key, no two ways about it. Of course there is also the view that DP were tied down in harmonic tradition while Led Zep was breaking boundaries.
I'll work at my hearing habits, I promise! I even bought the Nirvana album in its anniversary remaster and keep it in the car so I listen to it more often. Except that I don't and then end up listening to Taylor Swift's new album instead. I'm all weird I know!
