Jakob Bloch Jespersen acquired already as a boy his fundamental musical education, as well as his interest in singing, from his membership of the Copenhagen Boy's Choir. This led to studies at the Royal Danish Academy of Music, from which he attained his diploma in 2004, and subsequently to further studies at the Opera Academy of the Royal Danish Theatre, from which he graduated in 2007. Furthermore, he has studied privately with Hervé Niquet in Paris.
In 2006, Jakob Bloch Jespersen made his debut at the Royal Danish Theatre as Angelotti in Puccini's TOSCA and participated in the DVD and TV recordings of Carl Nielsen's MASKARADE as Magister Collatinus, in Britten's RAPE OF LUCRETIA at the intimate stage Takkelloftet, Basilio in Rossini’s THE BARBER IN SEVILLE at The New Opera as well as roles in numerous contemporary opera productions.
In spite of his young age, Jakob Bloch Jespersen has made his mark as a vocalist, both at home and abroad, with a repertoire stretching from baroque music to first performances of contemporary composers.
