    Dear SIS Community.

    From the theater, Østre Gasværk Teater, in Copenhagen we have received an inquiry, which we would like to share with you (Please see attached file in Danish).

    The theater is looking for a girl, 12-25 years of age, for the role as Clara in their upcoming music production VILDHEKS.
    The audition is scheduled for 4 and 5 March 2017, and more information about the audition can be found also in the attached file.

    Kind regards
    The SIS Administration
