The Zagreb Soloists (Croatian: Zagrebački solisti) is a chamber orchestra founded in Zagreb, Croatia, in 1953 through the auspices of Zagreb Radiotelevision, under the artistic leadership of the Italian cellist and conductor, Antonio Janigro. After Janigro left the ensemble in 1968, the group was led first by their concertmaster, Dragutin Hrdjok, and then by their longtime artistic director and concertmaster, Tonko Ninić. In 1997, Anđelko Krpan became concertmaster, and in 2002, Karlo Slobodan Fio, known for his beautiful vibrato, took over as artistic director of the ensemble. Since 2006, the concertmaster and artistic leader has been Borivoj Martinic-Jercic.
I Solisti di Zagreb have given over 3,388 concerts in all parts of the world, and are also very well known for their numerous recordings.
