Wozzeck is an opera composed by Alban Berg, which premiered in 1925 and is considered a pivotal work in the development of 20th-century classical music. The opera is based on the play 'Woyzeck' by Georg Bรผchner and tells the tragic story of a lowly soldier, Wozzeck, who descends into madness due to his oppressive environment and social injustices. Its unique blend of atonality, expressionist elements, and dramatic narrative make it a cornerstone of modern operatic repertoire.
