of Europe, leading to an influx of European musical ideas, the rural peasants maintained their own traditions, so that by the end of the 19th century Hungarian composers could draw on rural peasant music to (re)create a Hungarian classical style. For example, Béla Bartók and Zoltán Kodály, two of Hungary's most famous composers, are known for using folk themes in their music. Bartók collected folk songs from across Central Europe, including Romania and Slovakia, whilst Kodály was more interested in creating a distinctively Hungarian musical style. During the era of Communist rule in Hungary (1944–1989), a Song Committee examined and censored popular music for traces of subversion and ideological impurity. Since then, however, the Hungarian music industry has begun to recover, producing successful performers in the fields of jazz such as trumpeter Rudolf Tomsits, pianist-composer Károly Binder, and in a modernized form of Hungarian folk, Ferenc Sebő and Márta Sebestyén. Hungary has had several popular rock bands such as Illés, Metró, or Omega, of which Omega has remained relevant to the present with small foreign followings in Germany and elsewhere. Veteran underground bands from the 1980s such as Beatrice also remain popular. Literature In earliest times, the Hungarian language was written in a runic-like script (). The country switched to the Latin alphabet after being Christianized under the reign of Stephen I of Hungary (1000–1038). There are no existing documents from before the 11th century. The oldest written record in Hungarian is a fragment in the Establishing charter of the abbey of Tihany (1055) which, while mostly written in Latin, contains several Hungarian terms, among them the words feheruuaru rea meneh hodu utu rea, "up the military road to Fehérvár". The oldest complete text is the Funeral Sermon and Prayer (Halotti beszéd és könyörgés) (1192–1195), a translation of a Latin sermon. The oldest poem is the Old Hungarian Laments of Mary (Ómagyar Mária-siralom), also a translation from Latin, albeit a flawed one, from the 13th century. It is also the oldest surviving Uralic poem. Among the first chronicles of Hungarian history were Gesta Hungarorum ("Deeds of the Hungarians") by the unknown author usually called Anonymus , and Gesta Hunnorum et Hungarorum ("Deeds of the Huns and the Hungarians") by Simon Kézai, both written in Latin. These chronicles are a blend of history and legends, so they are not always historically accurate. Another chronicle is the Képes krónika (Illustrated Chronicle), which
