Rise and Fall of the City of Mahagonny (Aufstieg und Fall der Stadt Mahagonny) is a political-satirical opera composed by Kurt Weill to a German libretto by Bertolt Brecht. It was first performed on 9 March 1930 at the Neues Theater in Leipzig.

Time: Early 18th century
Place: Scotland
Act 1
Scene 1: The gardens of Ravenswood Castle
Normanno, captain of the castle guard, and other retainers are searching for an intruder. He tells Enrico that he believes that the man is Edgardo of Ravenswood, and that he comes to the castle to meet Enrico's sister, Lucia. It is confirmed that Edgardo is indeed the intruder. Enrico reaffirms his hatred for the Ravenswood family and his determination to end the relationship.
Scene 2: By a fountain at the entrance to the park, beside the castle
Lucia waits for Edgardo. In her famous aria "Regnava nel silenzio", Lucia tells her maid Alisa that she has seen the ghost of a girl killed on the very same spot by a jealous Ravenswood ancestor. Alisa tells Lucia that the apparition is a warning and that she must give up her love for Edgardo. Edgardo enters; for political reasons, he must leave immediately for France. He hopes to make his peace with Enrico and marry Lucia. Lucia tells him this is impossible, and instead they take a sworn vow of marriage and exchange rings. Edgardo leaves.
Act 2
Scene 1: Lord Ashton's apartments
Preparations have been made for the imminent wedding of Lucia to Arturo. Enrico worries about whether Lucia will really submit to the wedding. He shows his sister a forged letter seemingly proving that Edgardo has forgotten her and taken a new lover. Enrico leaves Lucia to further persuasion, this time by Raimondo, Lucia's chaplain and tutor, that she should renounce her vow to Edgardo, for the good of the family, and marry Arturo.
Scene 2: A hall in the castle
Arturo arrives for the marriage. Lucia acts strangely, but Enrico explains that this is due to the death of her mother. Arturo signs the marriage contract, followed reluctantly by Lucia. At that point Edgardo suddenly appears in the hall. Raimondo prevents a fight, but he shows Edgardo Lucia's signature on the marriage contract. Edgardo curses her, demanding that they return their rings to each other. He tramples his ring on the ground, before being forced out of the castle.
Act 3
Scene 1: Wolfcrag
Enrico visits Edgardo to challenge him to a duel. He tells him that Lucia is already enjoying her bridal bed. Edgardo agrees to fight him. They will meet later by the graveyard of the Ravenswoods, near the Wolf's Crag.
Scene 2: A Hall
Raimondo interrupts the marriage celebrations to tell the guests that Lucia has gone mad and killed her bridegroom Arturo. Lucia enters. In the aria "Il dolce suono" she imagines being with Edgardo, soon to be happily married. Enrico enters and at first threatens Lucia but later softens when he realizes her condition. Lucia collapses. Raimondo blames Normanno for precipitating the whole tragedy.
Scene 3: The graveyard of the Ravenswood family
Edgardo is resolved to kill himself on Enrico's sword. He learns that Lucia is dying and then Raimondo comes to tell him that she has already died. Edgardo stabs himself with a dagger, hoping to be reunited with Lucia in heaven.

Diana Damrau’s reputation as the world’s leading coloratura soprano has been built on her extraordinary technical virtuosity, her sensitive musicianship and her acute psychological insight. In Katie Mitchell’s sometimes radical production of Lucia di Lammermoor from the Royal Opera House, she is, as the Financial Times wrote, 'brilliantly convincing'. Award winning director Katie Mitchell took a revisionist approach to the drama, updating the action to the mid-19th century and applying a feminist slant as she added new and unexpected elements. Mitchell also made extensive use of a ‘split screen’ effect on the stage, counterpointing two different pieces of action at key moments.
