During the era of communist rule in Hungary (1944–1989), a Song Committee scoured 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 modernised form of Hungarian folk, Ferenc Sebő and Márta Sebestyén. The three giants of Hungarian rock, Illés, Metró and Omega, remain very popular, especially Omega, which has followings in Germany and beyond as well as in Hungary. Older veteran underground bands such as Beatrice, from the 1980s, also remain popular.
