Britten fathomed Phaedra's passion for her stepson in a shattering quarter of an hour's dramatic cantata. Euripides' Hippolytus takes about 90 minutes in the playing. Director Kryzsztof Warlikowski's fantasia on the Phaedra myth is more than twice that long, but it's worth every riveting or disconcerting minute thanks largely – but by no means exclusively – to the encyclopedic range of Isabelle Huppert.

Anger and fear in Elgar, introspection in middle-period Beethoven: these are undervalued qualities in each composer’s music. Yet such moods were vividly present in two hyper-nuanced interpretations last night. It was easy to believe that no other solo violinist in the world today strikes a finer balance between sweet tone in the upper register and overall strength than Nikolaj Znaider; and on this evidence it sounded as if Antonio Pappano, a perfect concerto partner and a master of symphonic light and shade, might have made an even better choice of LSO Music Director than Simon Rattle.

Sakari Oramo devised a bold programme for the final concert of the BBC Symphony Orchestra season: a new work from a young British composer, a popular but knotty violin concerto and an obscure pacifist oratorio. There were few obvious connections between the works, but all proved satisfying, not least for the excellent playing of the orchestra itself.

Laid low by a bug, Daniel Harding had to withdraw at the last minute from conducting the LSO last night. Booked as the soloist, Leif Ove Andsnes stepped into the breach to lead Mozart’s Piano Concerto No 20 from the piano, as the composer would have done. His unruffled keyboard technique and unimpeachably neat phrasing betrayed no sign of hasty preparation. Unfortunately they also barely scratched beneath the surface of a dark and troubled work that grabbed Romantic imaginations at a time when so much other Mozart was brushed off as Rococo plasterwork.

Banished from the Barbican are the hollow kings of the mediocre RSC Henrys IV and V. In their place comes a whole new procession of living, breathing monarchs in a vision that's light years away from bad heritage Shakespeare. Doyen of Dutch-Belgian - and world - theatre Ivo van Hove has filleted Henry V, the three Henry VI plays and Richard III to create his own trilogy of Greek-tragedy leanness and power, focusing above all on the totally different characters of three men making crucial decisions in times of civil, internecine and international war.

Last and most imposing of Bruckner’s completed symphonies, the Eighth invites and frequently receives architectural comparisons. Such talk of pillars and cathedrals could only be wide of the mark in the wake of this unconventional, beautifully prepared and deeply humane performance by the London Symphony Orchestra and their principal conductor designate, Sir Simon Rattle.

Masaaki Suzuki’s reputation precedes him. His recordings of Bach’s choral works with Bach Collegium Japan, the group he founded in 1990, have been arguably the finest of recent decades. But visits to the West, and especially to London, are rare, so this evening’s concert offered a valuable opportunity to find out what the dynamics are within the ensemble, and how they achieve such impressive results on disc.

The Barbican has built a steady reputation for almost unclassifiable large-scale art exhibitions, particularly in architecture, design and photography: they have been underestimated pioneers, often working in areas themselves under-scrutinised. Thus they often manage to surprise, and so it is here.

Some new operas worth their salt work a slow, sophisticated charm, but the handful that holler "masterpiece" grab you from the start and don't let go. Gerald Barry's shorn, explosive Wilde – more comedy of madness than manners – was so obviously in that league at its UK premiere in 2012, and has kept its grip in two runs of Ramin Gray's similarly against-the-grain production, now removed from the currently-closed Linbury Theatre at the Royal Opera House to the wider stage of the Barbican Theatre. It's still one of the few hysterically funny operas in the repertoire.

Art can inspire music, and vice versa. When concert (as opposed to theatre or film) scores are accompanied by images, however, the effect dilutes the impact of both; above all, the imagination stops working on the visual dimension created in the mind's eye.
