Marco and Christa have received standing ovations and numerous performance invitations for their stage chemistry and interpretation of operatic and operetta favorites, musical theater standards, art song repertoire, and classical sacred music. Both are natives of Southern California and received their advanced degrees in music from noted institutions in Los Angeles. They are co-administrators of Opera on Tap Vienna, Opera on Tap’s first chapter in Austria! Marco and Christa not only perform with orchestras and pianists for concert engagements, they have also performed numerous programs outside both a Capella and with pre-recorded accompaniment. They can easily give performances in a concert or recital hall as well as outdoor venues.
