What is "sinnamon"

Sinnamon was an American female R&B vocal trio, consisting of Connecticut natives Barbara Fowler and Marsha Carter, and Melissa Bell from New York. The group went through an abrupt development from a minimalist contemporary R&B sound of post-disco which was dropped after a third release, moving towards mild freestyle and radio-friendly house music but still preserving their R&B affiliation. Bell is currently a writer, living in New York City.
