Antonio Breschi, also known as Antóni O'Breskey (born in Florence, Italy, with Argentine roots) is a composer, pianist and trumpet player, singer, writer, poet and music educator.

[6] He has been breaking barriers among many different kinds of music, “yet he was the first to combine Flamenco, Basque, Arabic, Latin and Irish elements, his virtuoso jazz-styled piano uniting these traditions in remarkably original compositions.”[7] With his work "Orekan: The Ethnic Symphony" he created a new “symphonic” concept bringing together piano (the top classical instrument which started the new “well tempered” system) with a vast variety of "not tempered” instruments, belonging to many different ethnic traditions.

He is also known to be the inspirer of the show Riverdance: “Bill Whelan developed Breschi’s synthesis of Flamenco, jazz and Irish traditional strands as a key structure in his Irish music and dance spectacular, Riverdance.”;[9] “Well pre-dating Riverdance.”;[10] “Ahead of his time… in 1979 Antóni O’ released a track called “Sunrise”, some of which sounds almost exactly like Riverdance” (Victoria Clarke, Sunday Independent).

[12] He has written 4 books: “Ecologia: Salviamo Anche la Musica”,[13] “Semiminime”, “When Bach Was an Irish Man and Mozart a Gipsy Boy” and “Heyoka: Il Giullare dell'Anima”.

In addition to music, Antonio has dedicated a lot of time as an educator, social worker, writer, cook, actor, poet and has achieved a diploma in herbology.

[16] This name refers to the journey of the Irish emigrants to America and the meeting with the African people which, pursuant to Breschi's belief, gave birth to jazz.

He made many tours in Italy, Ireland and Switzerland with Irish musicians Máirtín O'Connor (De Dannan), Andy Irvine, Planxty, Dolores Keane (De Dannan), John Faulkner, Johnny McCarthy, Joe McHugh, Maurice Lennon (Stockton's Wing), Gerry and Annie O' Donnell, many of whom participated in Antonio's albums.

Recently Antonio appeared in Ireland in duo with singer Donovan and special guest Chris De Burgh, and with Eoin Dillon (Kila).

[20] Antonio created, performed and directed the fairytale "The Woman Of The Sea", also for children, produced by Teatro Comunale of Florence with the help of film directors Franco Piavoli, Ermanno Olmi and Mario Monicelli.

Later Antonio created a new version of it with Swiss theatre director Michel Poletti, produced by the International Locarno Puppets Festival.
