From the outset, Ernst Krenek stood between the sometimes antagonistic musical worlds of his mentor Franz Schreker, on the one hand, who wrote in the world of late Romanticism, and Arnold Schoenberg, on the other, who broke new ground. So, his own development towards becoming a unique personality in modern music history progressed correspondingly slowly. In his subsequent travelling years, as a composer he was on a quest for new means of expression, finally culminating in two such contrasting works as the jazz opera Jonny spielt auf and the technically strictly twelve-tone opera Karl V. Afterwards, he occasionally resorted to these earlier stylistic devices like we can hear on this recording as example of the 1927 composed Potpourri and years later written Tricks and Trifles (1945)
