He organized with René Heinersdorff a concert series, from 1991 to 2000, forum 20 – musik unseres jahrhunderts im spiegel der dezennien (forum 20 – music of our century mirrored in decades),[2] which focused on a fusion of the arts, both informative and entertaining.

[4] Colleagues composing for him and his kinderklavier included Christian Banasik [de], Oskar Gottlieb Blarr, Ratko Delorko, Michael Denhoff, Oscar van Dillen and Andreas Kunstein.

A memorial concert for him was played on 22 November 2015 at the Tonhalle Düsseldorf in the series for contemporary music Na hör’n Sie mal.
