The Five Orchestral Songs (German: "Fünf Orchesterlieder, nach Ansichtkarten-Texten von Peter Altenberg" ), Op.
 4, for medium voice and orchestra, were composed by Alban Berg in 1911/12.
 Numbers 2 and 3 were premiered under the baton of Berg's teacher Arnold Schoenberg at the Vienna Musikverein on 31 March 1913, known as the "Skandalkonzert" for the riot that erupted during Berg's songs.
 The texts are taken from picture-postcard texts ('Ansichtskartentexte' in German ) by the contemporary Viennese poet Peter Altenberg (hence the more commonly used title Altenberg Lieder ).
 The texts deal with the stormy but beautiful condition of the soul, and the palpable sensations of love and longing.
 Berg's setting is for a large orchestra.
 The music has many displaced ostinati and the conflicted, lyrical passion found in much of Berg's works.
The Alban Berg Quartett was a string quartet founded in Vienna, Austria in 1970, named after Alban Berg.
Wozzeck (op. 16) is a 1926 German-language opera in 18 scenes and one epilogue by Manfred Gurlitt after the fragmentary "Woyzeck" by Georg Büchner.
 It was premiered 22 April 1926 in Bremen, four months after the better known opera "Wozzeck" by Alban Berg had been premiered at the Berlin State Opera on 14 December 1925.
 The two composers were unaware of each others projects, being among many artists stimulated by the publication of Büchner's play.
 Berg, unsettled by his publisher Universal Edition also publishing another opera on the same material so quickly reviewed Gurlitt's piano score, and in a letter to Erich Kleiber noted Gurlitt's work's quality and originality, but found the "broth" watered down.
 This verdict reflects Berg's own Wagnerian influences, while Gurlitt was nearer to the aesthetics of Paul Hindemith and Kurt Weill.
Wozzeck (] ) is the first opera by the Austrian composer Alban Berg.
 It was composed between 1914 and 1922 and first performed in 1925.
 The opera is based on the drama "Woyzeck", which was left incomplete by the German playwright Georg Büchner at his death.
 Berg attended the first production in Vienna of Büchner's play on 5 May 1914, and knew at once that he wanted to base an opera on it.
 From the fragments of unordered scenes left by Büchner, Berg selected fifteen to form a compact structure of three acts with five scenes each.
 He adapted the libretto himself, retaining "the essential character of the play, with its many short scenes, its abrupt and sometimes brutal language, and its stark, if haunted, realism..."

"Schliesse mir die Augen beide" is a poem by Theodor Storm, twice set to music by Alban Berg.
 Berg composed his first setting in 1907, dedicating it to his future wife.
 The second version was composed in 1925 to celebrate the 25th anniversary of the Universal Edition music publisher.
 This second setting was Berg's first full-fledged 12 tone composition, and he re-used its tone row, or rather its secondary set, in the first movement of the "Lyric Suite" for string quartet of 1926.
Alban Berg's Violin Concerto was written in 1935 (the score is dated 11 August 1935).
 It is probably Berg's best-known and most frequently performed instrumental piece, in which the composer sought to reconcile diatonicism and dodecaphony.
 Berg composed it on a commission from Louis Krasner, and it became the last work that he completed.
 Krasner performed the solo part in the premiere at the Palau de la Música Catalana, Barcelona on 19 April 1936, after the composer's death.
