A composing pianist for whom the worlds of jazz and so-called classical music have from the very beginning been inseparably intertwined as a source of inspiration. For this reason, audiences encountered the keyboard artist with his trio or as a sideman at jazz festivals such as the Cologne Jazznight, Jazzahead Bremen, or the Düsseldorf Festival. At the same time, he presented his own projects on classical stages including the Konzerthaus Berlin, the Berlin Philharmonie, the Bad Kissingen Piano Summer, and the Musikfest Stuttgart. Several CDs and productions for broadcasters BR, MDR, and HR document his work with various ensembles.
Wienand began his training as a classical concert pianist with Marianne Bender (Calw), Prof. Friedemann Rieger (Stuttgart), and Klaus Eidmann (Detmold). He then attended the Würzburg University of Music, completing diplomas in jazz piano (artistic major with Tine Schneider) and classical piano (artistic and pedagogical major with Eva May). Masterclasses with Jacky Terrasson, Misha Mengelberg, Barry Harris, Hubert Nuss, Begona Uriarte, Karl Hermann Mrongovius, and André Marchand further deepened his education.
Wienand lives and works in Berlin as a pianist, composer, and teacher of piano, jazz piano, and theory/ear training.

Kempendorff has received several grants from the city of Berlin, was a DAAD-scholar from 2006-2007 in NYC and spent a month at the Stadtmühle Willisau in Switzerland as a guest of the Alfred-Köchlin-Foundation.
