The Pierces are a New York-based music band. The principal members are sisters Catherine Pierce and Allison Pierce, who originally hail from Birmingham, Alabama. Over the years, the girls have been compared to well-known artists like The Roches, Tori Amos, Sarah McLachlan, Shawn Colvin, the Indigo Girls and Sheryl Crow.

My friend Amanda Allen passed this on to me in the form of a Facebook comment; the song "Secret" is extremely catchy in an Edward Gorey / Tim Burton kind of way.  The rest of the albumm with titles such as "Kill! Kill! Kill!" are just as fun and whimsical.
