Wearing a mild disguise (a hoodie and sunglasses) R&B singer Brandy recently took to the New York city subway and started singing.
This is how she explained the experiment on her blog.
Recently, Frank Silent and I took a little subway ride after I'd left the gym. Frank, his camera, and I always equal a good time. I decided to hit the subway and sing my little heart out. You've [sic] fun-filled morning left me asking: Can a Sistah get ONE fan?!"
As you can see, nobody recognizes the former Moesha star, even when she starts talking and pleading for attention. One man is nice enough to tell her she has talent. But he still has no idea who she is.
At this point, it may be that Brandy is the less famous sibling.
