The chamber music works of Detlev Müller-Siemens presented here were created between 2002 and 2009. In them, the serenity and thoughtfulness of the form contrast with the inner turbulence that comes from a musical language that is "on it's own" and does not follow any pre-existing patterns.Müller-Siemens said about his "String Trio" which he dedicated to the Mondrian Ensemble: "The first movement is torn, disjunct, often motoric, and in it's course characterized by sharply contrasting sections which are parts of several very different structural layers. In contrast, the second movement is more unified: a fragile, hesitant, ascending melody upon which a 'presto-lamento' passage is briefly superimposed toward the end."In the piano quartet "lost traces", also dedicated to the Mondrian Ensemble, "the music searches for traces in order to find it's way. It follows these traces, but loses them again, so that the music must pause, disoriented - moments in which the music seems to be entirely by itself and to have found itself - before taking up the search again."
