I think there's a lot of room for interesting music between 3 chords and the truth songwriter types ala Tom Petty and guitar virtuosos like Yngwie Malmsteen who only view a song as a platform on which to jerk off 64th notes out of their fretboard. I don't know enough about Tim Henson to know where he might fall on that spectrum, but I'd be surprised if he isn't a lot closer to the latter than the former.
What interests me are elaborate, varied compositions involving excellent musicians. Like, my favorite band is probably Yes, and "Heart of the Sunrise" is my favorite song of theirs. I can put that on over a good pair of headphones and it takes me on an 11 and a half minute journey where the world fades away (gummies help). I can't recall a single line of lyrics from it. I vaguely have ascertained its about being lost in a city, but its kind of silly if you were to just read the lyrics. But Jon Anderson has such a great voice, it doesn't matter. He could sing "Row, Row, Row Your Boat" with the same melodies in the song and it would still be incredibly beautiful and moving to me. And yeah, there is some virtuosity on display, at times.
I am sure a lot of people would listen to it and have the reaction that its just a meandering, self-indulgent mess. And that would be a perfectly valid opinion. Don't care, had ear sex.
