The Edinburgh Festival is a huge event and a potentially overwhelming experience, and anyone could use a hand in selecting which concert might be their best bet, and which one they should avoid like the plague. The ever-helpful Michael Tumelty is on hand to point out that this year’s fest features a performance by a Hungarian orchestra of what nearly everyone agrees is the worst concert piece ever written by Richard Strauss. It’s just mind-numbingly awful, simplistic, and clearly tossed off by the composer while he waited for something better to do. So which concert would Tumelty recommend you not miss? Yeah, um, that one.
