▶ How can one man create that huge amount of relevant music?
I'm still sleeping.
▶ Is it true that ›Ein Dutzend Etüden für Gitarre‹ was designed to overcome aviophobia?
Not really. But while having a lot of educational aspects in the first place, that effect you mentioned has been reported to me from people all over the world who played the etudes. By the way: try travelling without moving, for a change.
▶ Will one die upon playing your ›Five Fatal Pieces‹ for guitar?
Not at all. Care has been taken.
▶ Your favorite BR song?
›Struck a nerve‹.
