For his master's degree, Strothmann researched and wrote about the network of jazz music in Europe, for which he visited and lived in London, Dublin and Brussels.
These interviews, with concerts and lessons he took during his research, gave him an understanding of the structures of jazz music and performance across Europe.
He was interviewed by Linley Hamilton of BBC radio and talked about the Transitions Organ Duo and his research activities.
Strothmann plays gigs at high-profile jazz concerts such as “WDR Jazznacht” in Gutersloh [2] and “Wacken”.
On the Transitions album “No Idea” (2013),[3] Jeanfrançois Prins (guitar) and Frederik Köster (trumpet, winner of the German Jazz Echo prize),[4] joined Transitions on Strothmann's compositions “Emerald” and “No Idea”, and Prins’s composition "Futebol".
