A gazillion years ago when I was the monitor engineer for a Shawn Colvin concert, the opening act was this teenager named Rebecca Correia

...she absolutely killed. I don't normally remember the names of one-off warm-up acts 10 minutes after their set ends much less several years after the gig, but Rebecca's name really stuck with me. She was such a professional with stunningly well crafted original tunes and a delivery that was exquisite. I'm not sure how her career's proceeded since then (I just Googled her & it looks like she's still at it Rebecca Correia ) but she's practically the only artist I'd bother naming in a "I love chick singers" thread.
