 The theater is known to have performed not only dramatic theater but also operatic plays and ballet, creating not only the first native actors but also opera singers and ballet dancers - whose identity, however, is mostly unknown.Elisabeth Lillström was a part of this diversity, and though never formally referred to as an opera singer, she was a soprano and frequently used in singing parts as well as theatre plays, and played an important part as an acting singer.In the 1747–48 season, Elisabeth Lillström starred in the main role of the nymph Syrinx in "Syrinx" by Lars Lalin or Peter Lindahl with music by Johan Ohl, opposite Peter Lindahl (as Harlequin), Johanna Embeck (Chlorix), Petter Stenborg (Philemon), Trundman (Sylvanus) and her daughter Elisabeth Olin (Astrild), which is known as the first Swedish opera comique.
