The Cave is a multimedia opera in three acts by Steve Reich to an English libretto by his wife Beryl Korot.

The Cave of the Patriarchs is of unusual interest in that it is a sacred place where Muslims, Jews and Christians pray.

The music and a major part of the libretto in the opera is derived directly from, and includes spoken responses from, Israeli, Palestinian and American interviewees who were asked questions about the story of Abraham.

The opera uses recorded speech as a source for melodies, a technique that Steve Reich first used in the 1988 Different Trains.

The main narrative thread that runs through the opera is the story of the life of Abraham, as it is told in the various religious texts, and how this story is now understood and interpreted, using modern-day accounts by individual people from three different major religious and cultural contexts.
