Bayreuther Tannhäuser approaching fast: Who is Sebastian Baumgarten?

The other day I discussed the revival of Les Brigands at the Opéra Comique in Paris, and I realized that a German version of this work [well, "inspired by this work", would be more accurate a statement ;)] was produced last year at the Theater Neumarkt in Zurich by Sebastian Baumgarten -- yes, the same guy who is in charge of this year's opening show of the 100th Bayreuther Festspiele, Tannhäuser, to be premiered on July 25.
