In March 2018 Oulu Music Festival again brought interesting international and Finnish artists to Oulu. For example, world-famous soprano Karita Mattila performed together with Oulu Sinfonia, and Kauko Röyhkä and Severi Pyysalo played together with Oulu All Star Big Band.
The international guests included American jazz violinist Zach Brock and jazz pianist Phil Markowitz. Chamber music concerts were organized in different venues from private homes to art galleries, and there also was a chamber club evening in a restaurant.
