I saw a TV show a few years ago about an indie rock female vocalist and guitarist (?) that formed a band and went on tour. The singer was dark haired and attractive. She pulled musicians from well established bands. It was a documentary or reality type TV show that followed them on tour. I remember it was on around the same time that Lisa Loeb's E! Online show was on called "Number 1 Single," so in the 2006-2007 time frame. I remember one episode where they played a gig in Las Vegas. Can you help with musicians name or TV show name?
