It features 15 jazz groups playing 28 shows.
Most musical performances during the festival, which runs until Monday, are free and will be performed on the streets of the picturesque west Cork village and in its pubs and cafes.
Headlining the festival are the Liane Carroll Trio and the Andreas Varady Trio. Thirteen-year-old Varady, who has been hailed as a brilliant jazz guitarist, will perform tonight in the Community Hall.
Tomorrow night, Liane Carroll, winner of the BBC’s Double Jazz Triumph for Best Vocalist and Best Jazz Artist, will take to the stage in the Community Hall, also at 8pm.
Back by popular demand, the Festival Club will be running on both Saturday and Sunday, beginning at midnight.
Clare-based jazz funksters, Earthship, play on Saturday night and will be joined by special guests to keep the dancefloor going until the early hours of the morning.
On Sunday night the Niwel Tsumbu Band will take to the stage, offering original Afrojazz fusion, a high-energy, virtuosic and funky sound that will make for a memorable night.
The remaining acts will fill the streets and pubs throughout the weekend.
Of particular note are the Bourbon Swing Jazz Band from Belfast and the Swingin’ Bluecats. Playing in the best New Orleans tradition, Bourbon Jazz’s influences range from King Oliver and Jelly Roll Morton to Louis Armstrong.
The Swingin’ Bluecats is a six-piece jazz ensemble that is a regular at the Cork Jazz Festival and is renowned for its signature style of blue zoot suits, with a playlist of jump, jive and swing music, and are always a crowd pleaser.
Daytime events include music sessions, a street market, street buskers and a youth music workshop.
