This year we are very excited to present our Jazz Weekend Showcase at the fanatstic Coughlans Bar on Douglas Street. We have 30 singers performing Jazz & Soul classics from Etta James to Eva Cassidy. We will also feature a perfomance from our Adult Performers Workshop who have helped co-ordinate this event. What is Cork Jazz Weekend? The Cork Jazz Festival is an annual music festival held in Cork City, Ireland in late October every year since 1978. The festival is Ireland's biggest jazz event and attracts hundreds of musicians and thousands of music fans to the city each year.
