She's played the ultimate girl gig, Lilith Fair, opened for folk legend Ani DiFranco and released her second album, "Smashing the Serene," on her own label. Self-taught singer/songwriter/pianist Rachael Sage -- known as Karen Weitzman in her Stanford days -- is making a name for herself with eclectic tunes and ornate stage costumes. Winner of the 2000 John Lennon Songwriting Contest and a regular performer at New York City's Sidewalk Cafe, she says it's an honor and a challenge to play to live audiences. Says Sage: "It's an opportunity to pin down your essence on a daily basis and uplift people." Rock on.
