I want to follow up. YouTube is great for hearing music, right? Two recordings of her post-Sergio career do sound great: "Hello It's Me" (Todd Rundgren) And the "Love Song" from her first solo album sound really good too. I wouldn't describe the style of the backing (instruments and production) to be banal at all in those two selections. I suppose a more refined and adult sensibility is needed to properly appreciate it (which I now have). Her singing had a purity that was free of excessive ornamentation and forced self-consciousness or showing-off or anything. She really served each song she sang. If only her solo albums had more great songs!
