In practice as well as in prospect, the second in Riccardo Chailly’s Strauss/Mozart trilogy was a concert of two very different halves. The first offered small Bavarian and Austrian beer in the shape of Strauss’s fustian Macbeth, unbelievably close in time to the masterly Don Juan which blazed on Tuesday, and a pretty but just a little too anodyne Mozart violin concerto at the other end of Mozart’s prodigious composing life to the last work for piano and orchestra, which had amazed us in the first concert.

Riccardo Chailly’s Strauss odyssey with his Leipzig orchestra peaked in Saxony last year, the 150^th anniversary of the composer’s birth. I was lucky to catch a razor-sharp Till Eulenspiegel and a saturated Death and Transfiguration in Dresden’s Semperoper close to the birthday. 14 months on, and the Barbican has nothing like the same necessary air to offer around a mini-residency of richly-scored symphonic poems.

Stunningly reinvented in series four, Homeland sustained the momentum with this tense and menacing fifth season opener. Carrie Mathison (Claire Danes) has now quit the CIA for a new job in Berlin, where she's working as head of security for billionaire philanthropist Otto Düring (Sebastian Koch). The past, however, is not giving up without a fight.

Not a ray of sunshine illuminated the landscapes that were explored in this stormy programme, the first of a three-part history of the Celts. It aimed not only to show the latest investigations into the Bronze and Iron Age tribes who inhabited Europe from Turkey to Britain but to suggest their culture was richer than the simple cliché of barbarians at the gate.

An encounter with Hamburg’s Reeperbahn is akin to assimilation into a real-life kaleidoscope where bright lights, mass revellers and shills touting bars, night clubs or strip joints combine in a single multi-sense overload. The tumultuous thoroughfare is dedicated to excess.

A concert of Brahms chamber music I could understand, especially given a balance between early and late. An evening of orchestral Brahms, with or without voices, needs much more special pleading. It didn’t get nearly enough last night. An expanded Orchestra of the Age of Enlightenment, including nine very vigorous double basses – where did the extra players come from?

It felt a bit like we were seeing things. At the fag-end of Edinburgh’s 2015 August of festival mayhem, with extreme exhaustion and input overload mixing to brain-addling effect in the heads of most festival-goers and participants, a hallucinatory, day-glo farce of a show that obsessively repeats just a single word seemed pretty fitting.

The plot to assassinate Hitler that everyone knows about was on 20 July 1944. It had its Hollywood moment in 2008 with Bryan Singer’s Valkyrie, starring Tom Cruise as Colonel Von Stauffenberg. That film unfortunately arrived on the coattails of Downfall, which has since made all Anglophone portrayals of the Third Reich look dismally bogus. So it’s of note that Downfall’s director Oliver Hirschbiegel, having taken leave of his senses to make Diana, has turned his attention to the lesser-known attempt on the Führer’s life.

Fair exchange? German humour, perhaps? We send Her Maj off to the Fatherland for a State Visit, and the Embassy of the Federal Republic in London reciprocates by bringing us the popular singing phenomenon – “national institution”, as he was described in last night's introductory speech – Max Raabe, for an early celebration of 25 years of German reunification.

Heimat was already one of cinema’s most extraordinary, majestic achievements. Edgar Reitz’s three series of films for German TV spent 53 hours exploring the humanity of the inhabitants of Schabbach, a Rhineland village much like Reitz's own roots, throughout Germany’s cataclysmic 20^th century. It was a chronicle built from often fond, sometimes horrifying memories, mesmerically deep, leisurely detail, and a gorgeous cinematic eye. Reitz was 79 when he added nearly four further hours, revisiting Schabbach in 2012. This could have been hubris.
