Behind the name «Etablissement public Salle de Concerts Grande-Duchesse Joséphine-Charlotte» are two entities with two different histories: the Orchestre Philharmonique du Luxembourg founded in 1933 and the Philharmonie Luxembourg, a concert venue opened in 2005. In January 2012 the two institutions merged both artistically and administratively. The Philharmonie has succeeded, in a very short space of time, in establishing itself as a much-loved venue for music-making and listening – both in Luxembourg and internationally. This success owes much to its exceptional architecture by Christian de Portzamparc and its impressive acoustics by Albert Xu. Wide-ranging musical diversity and an uncompromising attitude to artistic quality are the guidelines for programming at the Philharmonie which hosts some 400 concerts and events every year in various genres, such as classical music, jazz, world music, contemporary music and children's concerts. The acoustics of its residence, its long-standing relationships with other prestigious halls and festivals as well as its close collaboration with first-rate musical personalities have contributed to making the Orchestre Philharmonique du Luxembourg an orchestra renowned for the elegance of its sonority. Its standing has been confirmed by an impressive list of prizes awarded for some twenty CDs, including a Grammy Award with Angélique Kidjo and Gast Waltzing.
