After answering mostly in the negative to this question by agreeing with another poster who had already said what I was going to say, I have to admit that there are a couple of artists that came to mind last night.
Pixies - this is a really, really different kind of a rock band. When I told people I was intrigued with Pixies they suggested I listen to Sonic Youth. Not even close in my opinion. Frank Black’s mind is not stuck on the usual topics, and his musical insights are quite unique to my ears. Nobody else is doing anything like that. The latest stuff from the Pixies continues in the tradition, not re-treading old ground but similarly exploring new perceptions of our culture and life in general, and expressing them musically and visually with videos.
James Booker - as Hugh Laurie said in this video interview "He’s making connections all the time, musical connections and emotional connections, and heading in directions that - other people, it just wouldn’t occur to them to do."
I think those same words apply to Frank Black as well, even though Frank isn’t even close to the technical prowess of James Booker. Hardly anybody is. That really doesn’t matter as much to me as the ability to communicate ideas through music. There are deep connections intertwined in the music. Maybe other music does this kind of thing just as much but I don’t pick up on those connections as well as I do with Frank and James. Or maybe I’m just not as interested in the topics most of the time. So I guess they are thinking about many of the same kinds of things I am, and effectively expressing them in music.
