Marek Polanski's album is the world phonographic premiere of the first Polish violin caprices by August Fryderyk Duranowski and Joachim Kaczkowski.

The recording was made on the 185th death anniversary of August Fryderyk Duranowski as well as on the 230th birthday and 190th death anniversary of Joachim Kaczkowski. Its premiere falls on the 250th birthday anniversary of August Fryderyk Duranowski in 2020. All these anniversaries are a great opportunity to familiarize music lovers around the world with the works of these two composers, now almost completely forgotten.
