These 4 jazzy-type pieces are really tricky but quite delightful. Blaz Pucihar is a Slovenian composer and although this work is clearly not based around Eastern European folk music it is certainly fun to play and easy to listen to. It is described as 'friendly' in the publicity - very apt I think.
Difficulty level, roughly compared to ABRSM exam grades. 0 is beginner, 9 is advanced (beyond grade 8).
