I went to Hannover to take a portrait of the music ethnologist Prof. Raimund Vogels. His department probably has one of the the largest collections of worldmusic. They have recently rescued a collection of nigerian music from the university of Abuja, where it was under constant threat from Boko Haram. Most of it is in vinyl! So the main job of his two student assistents is to digitalise the collection. In real time.
