“Modern repertoire continued the Hungarian lineage. The variability of fingerprints was the theme of Georg Hajdu’s composition with the same title. A musical kit which allowed the pianist to build the composition from acoustic fragments and segments… Contrasting dynamic and sound effects went along with planned goal-orientedness. A work that—unlike many other modern piano pieces—didn’t fail to show individual expression.” (Westfälische Nachrichten, October 1997)
