Another good friend of mine sent me an email suggesting this song. He has impeccable taste (despite his dislike of Tom Waits and Nick Cave). I have always loved their harmonies and intertwined vocals.
Amy Ray and Emily Saliers have known each other since elementary school just outside of Decatur, Georgia. They started playing together in high school, but then went off to seperate colleges - temporarily. They eventually both transferred back home to Emery University and by 1985 had started playing together again as Indigo Girls (a name they picked while going through the dictionary and deciding they liked the word "indigo").
Galileo by the Indigo Girls from the 1992 album "Rites of Passage"
To see the official Sony-BMG released video for Galileo (it's unembeddable, sorry, but I still recommend it), you can go straight to it by clicking HERE.
