When about a year ago, I resolved to acquaint myself with Robert Lamm's solo oeuvre in the decades past his first effort (Skinny Boy), somewhere along my survey I came to his 1999 album, In My Mind, and I was so pleased to see he had duets there with the great Phoebe Snow (she died before her time in 2011). Lamm's two songs he crafted for his duets with her are tenderly sophisticated pop jazz, perfect vehicles for her vocal creativity -- "The Best Thing" and "Swept Away". Not only are the styles reflective of Lamm's continual openness to music genres over time, but I even notice the way he sings on for example "Swept Away" shows he's been listening attentively to the changing music scene (at that point, of course 1999) and adapts & blends it into his own unique vocal tonality.
I'd been a fan of Phoebe Snow for years, and find especially her two albums Second Childhood and Never Letting Go -- to be her best. It was quite a treat to hear her work with Lamm. And in "The Best Thing", particularly toward the end, their voices together produce a very sonorous match.
