I think for all of us there are two different kinds of music we may or may not enjoy.
For the most part, and myself, have music I listen to when I'm happy, music that makes me feel ecstatic, no worry in a world, having a great time, strong, slick, etc. We all have music like this that we enjoy, the kind of music we can share with our friends and listen in the car.
There is also music for some of us that is very personal, spiritual, that leaves us vulnerable, exposing our fears, our dreams, inspiring true love, deepest sorrow. This is the kind of music you don't normally find on the radio, the music you don't normally share aside from a few that are very close to you. The kind that makes you think and after you listen to it, you feel like you are a different person entirely, or at least, it inspires with a sense of truth, a sense of real life experience, sentiment, nostalgia, reflection. I'm not sure how to describe it.
For me, for the past two years, the band I keep discovering and re-discovering that fits both catagories, but maintains a sense of experience and reflection, sometimes ecstatic, sometimes despairing absolutely, would be the Cure. It was a band started in the late 70s and continues to make albums, though their most notable expansive, profound effort was the Disintegration album (winning them Best British Band in the early 90s).
Depending on my mood, there is always an era that reflects it, and in a poetic way I've never been touched with before, they have been able to express things to deeper then I, at least, never thought possible. None of their albums are the same at all, and they experiment with new styles maintaining a refreshing sound throughout their careers. They of course had their albums I don't like as much as others, some that took a long time to grow on me.
But if you have ever heard a song that seems to lift your spirits so much that you want to simply laugh it out, or a song that has made you want to cry with it's sad, truthful beauty, this is largely how I feel about this band. It has changed how I understand and feel about love. And oh so often it seems when I wake up feeling like the world has become a mess I can't pull apart, like waking up from the dream of yesturday--it has gotten so complex! I never understood it--and then clarity.
Yuki Kajiura is the only artist that feels the same way, as if the music is being made just for you. Like when you hear that song on the radio, and the guitar is going wild, but it never goes as wild as you would have liked, yet this band does everything to a dramatic satisfaction you have always been looking for. It achieves everything creativily that you always hoped it would. It's not trying to be anything, it just is, and it seems to reflect everything you have ever felt, something you feel you can understand, with a strange power and deep complexity, touching your truest thoughts and hopes.
