"As an improviser, you often find that it‘s not the compositions themselves you‘re playing, but your own memories of them. And as these memories come back to you in the moment, they assert their continuing existence in the here and now," says Michael Wollny. In other words, songs are like ghosts. Wollny‘s new album "Ghosts" is a gathering of some of the ghosts that regularly haunt him. Typically for Wollny, they range from classics like Franz Schubert's "Erlkönig" to jazz standards, film music, songs with a certain fragility by Nick Cave, say, or the band Timber Timbre, and also include his own darkly evocative original compositions.
