The premiere performance of Rhapsody In Blue on 12 February 1924 is considered to be one of the most important musical and cultural events in American history and the one that rocketed George Gershwin to fame. It signalled the birth of Symphonic Jazz, a combination of American Jazz and the musical traditions of Europe. It is a loose and freely moving piece, unconstrained by formal structure comprised of motifs and ideas. With more than 1,200 titles from the orchestral and choral repertoire, from chamber music and musical theatre, Edition Eulenburg is the world's largest series of scores, covering large part of music history from the Baroque to the Classical era and looking back on a long tradition.
