Sebastián Modarelli studied at the National Conservatory of Music in his native Buenos Aires, Argentina, earning his degree as salutatorian of his class. Besides earning an additional degree in Composition, Europe gave him the opportunity to participate in seminars and master classes with composers such as Karlheinz Stockhausen, Luis de Pablo and Marco Stroppa.
In 2005 Modarelli moved to Rochester, Minnesota after being offered the position of Music Director and Organist at St. John the Evangelist Church. His music has been performed and broadcast in different countries, including on MPR in the United States. In November 2013, the VocalEssence Ensemble Singers, under the direction of Philip Brunelle, premiered What I Have Seen and Heard, an hour long a cappella work entirely based on St. John’s Gospel, and commissioned on the occasion of the 150th anniversary of the Church of St. John the Evangelist (Rochester, MN).
Besides his ongoing organ performances, he has been involved in other numerous professional commitments. He has served as Dean of the Southeastern Minnesota Chapter of the American Guild of Organists, and he has recently been appointed as a member of the Liturgical Commission of the Diocese of Winona. In 2009, Alliance Publications contracted with him to begin publishing his work in the U.S.
