Ahh, Sparks! Those three 70's Island albums, Kimono My House/Propaganda/Indiscreet are three towering works of genius that I still listen to a lot. I'm warming to you Thor.
That's nice. However, I tend to lean more towards their newer material myself. Late 80's and onwards.
I've tried, I have the Lil' Beethoven disc, which I can admire without really warming to. For me they've lost that 70's magic, but then you can't be that brilliant for long.
