As end-of-term concerts go, Mahler’s Eighth Symphony is a biggie. In fact it’s hard to imagine any place of secondary education where they would even contemplate it.

The festival Summer Music in City Churches is in only its second year, filling a gap left by the demise of the long-running City of London Festival.

Emanuel Ax here celebrated his 70th birthday with an all-Schumann recital. In fact, it was an all-Schumann marathon, a three-hour concert at Wigmore Hall featuring solo works, Dichterliebe with Simon Keenlyside, and, with the Dover Quartet, the Piano Quartet and the Piano Quintet.

Treatise by Cornelius Cardew is the defining work of the graphic notation movement. The score, completed in 1967, is made up of 193 landscape pages, each with two empty musical staves running along the bottom, with an array of graphic designs above, often incorporating elements of musical notation, but rarely specifying pitches or rhythms.

The Barbican Hall hardly boasts the numinous acoustic of Gloucester Cathedral for which Vaughan Williams composed his Fantasia on a Theme of Thomas Tallis, but Sir Simon Rattle has long known how to build space into the architecture of what he conducts.

Having played their first concert just four years ago, the Chineke! Orchestra gave a rousing, exuberant performance for an ensemble still in its infancy. It’s a young orchestra, not just in the sense of only being founded a few years ago, but one that comprises many young players too. Though its youthful passion and energy was very much to the fore, there were some points in Edvard Grieg’s Peer Gynt Suite No 1 when a lack of experience let them down.

With two German giants roaring - Brahms in leonine mode, Richard Strauss more with tongue in armour-plated cheek - it could have all been too much. Not in the eloquent hands of the Royal Philharmonic Orchestra's Music Director Designate, Vasily Petrenko, or pianist Denis Kozhukhin, the most musically disciplined of Russians.

It wasn’t really the orchestra’s night.  Nor the soloists'. Nor, even, the conductor's. The Royal Liverpool Philharmonic Choir totally stole the show, well surpassing the incredibly high standards which they already regularly attain and performing not as a large symphonic chorus but as a something akin to one of the highly specialist choirs with which this country is blessed.

Esa-Pekka Salonen and the Philharmonia kicked off their series of concerts devoted to the edgy culture of the Weimar Republic with a programme that featured three works (out of four) derived in some way from the musical stage. That included, as a rip-roaring finale, the conclusion to Shostakovich’s football-themed ballet from 1930, The Golden Age. Given the theatrical energy that drove the evening along at the Royal Festival Hall, it felt at the outset slightly disappointing that we would see no (non-musical) drama on stage.

It’s quite a weighty concept, and one which could easily have buckled had both the music and its execution not been of the highest quality. Aurora Orchestra’s "Music of the Spheres" was a concert inspired by the Greek philosopher Pythagoras’s theory that each of the planets in our solar system must emit a particular sound through its orbit. The story goes that while passing a blacksmith at work, Pythagoras noticed that the sound produced by two anvils of differing weights was the same, though an octave apart.
