An "Original Cast Recording" is an audio album that features the performances of the cast from a specific theatrical production, typically a musical. These recordings capture the songs and dialogue as performed by the original actors, preserving their interpretations and vocal styles. They serve as a way for audiences to experience the show even if they cannot attend a live performance. These recordings are often released shortly after a show's opening and can become popular, sometimes leading to increased ticket sales. They are an important part of musical theater history, allowing future generations to appreciate works like Hamilton or The Phantom of the Opera.
