Story behind the song: For this week's video we decided to challenge ourselves. We picked a pop tune at the top of the charts -- one that wouldn't be an obvious candidate for an instrumental cover. "Rolling in the Deep" jumped out at us. The writers, Paul Epworth and Adele, described it as a "dark blues-y gospel disco tune." What could be more challenging for a classically-trained cellist and pianist? We locked ourselves in the studio (ok, not literally) and began work on the introduction. It wasn't working. The end. Just kidding...:-) The song came alive when we found a destined matchup in the melody from Gustav Holst's classical piece "Jupiter"—a deep melody that rang out when layered on top of everything we were creating for this arrangement. To make a long studio-story short, it all came together after that. ALL sounds were created by acoustic & electric cellos (5 different cellos) and piano. By the time we were finished we had used 60 tracks.
