Yes - Roundabout - Fragile
I've had the bass line to the 2nd theme stuck in my head all day. And it is a killer bass riff, and bass tone.
It's still amazing to me how organic these early prog albums sounded. And how much they managed to layer with very early multi-track technology. These were probably 8-, or possibly 16-track recordings, and mixing desks with no automation. Nowadays we have almost unlimited ProTools sessions with track counts in the hundreds, and they still don't sound nearly as crisp or interesting.
