The 400 Roséens who returned to school to study found that the atmosphere was particularly lively this year thanks to a remarkable Back to School concert.  Naturally 7 provided a striking contract to the the classical concerts with the St Petersburg and Berlin Philharmonic orchestras that will take place later this year.  This world-renowned vocal play and a cappella group started off the year and the concert season with a vibrant performance that had everyone on their feet —  and most of them dancing.
