Marié Digby Sings "Gimme More"

Best known for her rendition of Rihanna's "Umbrella" on acoustic -- here she's singing Britney's "comeback" single...

A Los Angeles native and former UC Berkeley attendee, she recently drew controversy for using YouTube to get her name out à la LonelyGirl15. It worked. Local radio station STAR 98.7 started plugging her single and it soared in sales on iTunes as a result. You can currently catch her touring the country in small venues.
