I must admit to feeling, briefly, just a little disappointed on first sight of Maggi Hambling’s Walls of Water, nine new paintings on show at the National Gallery. Perhaps it was the evocative title, which promises high drama and instant gratification, something obviously and extravagantly impressive. In short, I was expecting something bigger, an absurd statement because eight out of the nine canvases measure more than six by seven feet. And yet, they are small.

If there's one commonly-known fact about Jackson Browne, it's that (with a bit of help from Glenn Frey) he wrote "Take It Easy" for the Eagles. The first track off their first album, and their first hit single, it remained a trademark for the band despite all the changes they subsequently went through. The following year, 1973, Browne released his own recording of "Take It Easy" on his second album, For Everyman. While the Eagles' version was harmony-packed and radio-friendly, Jackson's version was more introspective and philosophical, as much of his work tends to be.

Søren Nils Eichberg’s new opera Glare is advertised as a “taut” thriller. It’s actually a short thriller. Big difference.

The question of whether or not opera – a medium that wouldn’t win any prizes for sprinting –  can successfully pull off a thriller – a genre that lives and, more often, dies in its dramatic agility and lightness of foot – is a very real one. I’ve never seen it succeed yet, but would be delighted to be proved wrong. Glare, unfortunately, is not that proof.

Of course unavoidable circumstances do strike, and concerts do get delayed, but it’s astonishing just how often those circumstances seem to conspire against Valery Gergiev. Last night’s UK premiere of Rodion Shchedrin’s opera Levsha – the second night of a Mariinsky triptych of performances at the Barbican – started a nice round hour late, which was a real shame because once the drama shifted from offstage to onstage the work revealed itself as a bit of a gem.

When gifting the unheard a voice, the temptation is often to make it a solemn one. Thankfully, Paddy Campbell has, for the most part, sidestepped puritanical preaching in his debut play based on experiences working at a ‘wet house’, a homeless hostel where incurable alcoholics can drink in a secure environment. Though tonally uneven, at its best Campbell’s piece delivers unpalatable truths with a bitingly funny sweetener.

The first time I interviewed Richard Tognetti he told me a story. Prior to touring the Australian Chamber Orchestra to Japan, the group’s leader and artistic director was discussing publicity with a local PR. Faced with disappointing ticket sales he asked for advice. The response? Remove two letters from the orchestra’s name and transform it into the Austrian Chamber Orchestra – problem solved. It was a tale told with a smile and a roll of the eyes, but one that still had a frisson of Old World/New World truth about it.

Do not miss this film. I don’t say it lightly. Even on the small screen, filmmaker Jim Jarmusch's Cannes Palme d'Or nominee is a warm love story, no, a cool vampire tale, no, a wry comedy, no, all of these things in Only Lovers Left Alive. Stealing the title from David Wallis' 1964 science fiction book, this is an adaptation of Mark Twain’s satire The Diaries of Adam and Eve for the undead, and the casting couldn't be better. It's a film of mood and wit, of profundity and imagination: watching Only Lovers Left Alive will put you in a delicious mood.

Tricky has consistently displayed the genius of the self-taught DIY music magician and his latest album, a varied collection of sounds sombre, mysterious, melancholy and ceaselessly surprising, proves his continued worth as one of the most creative of the ground-breaking musicians who emerged from Bristol in the 1990s.

School’s out for summer, even Parliament is on recess, and the streets around my house are suddenly devoid of children, as families make for the hills (or at least the beach). It should be dead season for all but prommers (and the suffering residents of Edinburgh) but ballet in London has had the most extraordinary week of first-class acts, with the Mariinsky at the Royal Opera House, Sylvie Guillem and Russell Maliphant at the Coliseum, and now the BalletBoyz’ 10-strong troupe The Talent at the Roundhouse in Camden.

Last night’s performance of PUSH at the London Colisem left me exhilarated and downcast in equal measure. Exhilarated because dancer Sylvie Guillem, dancer/choreographer Russell Maliphant and lighting genius Michael Hulls together create the Holy Grail of dance, a blend of intelligence, talent and charisma so stunning and convincing that it seems to trascend description and become sacramental. And downcast because this run is the last of PUSH in London, and so for most of us the last time we’ll ever see it, or perhaps even see Guillem or Maliphant perform.
