Camille O'Sullivan: Changeling, Assembly Rooms *****

The Assembly Rooms may have reopened for this year's Fringe following a very swanky refurb, but someone obviously forgot to put sufficient thought into the practicalities of getting people in and out during the festival. The opening night of Camille O’Sullivan’s brief sold-out run started 40 minutes late after a chaotic queuing system apparently devised in tribute to MC Escher left much of the crowd – which, thrillingly, included Les Dennis – more than a little testy.

Diamanda Galas is a woman who once wrote a book called Sh*t of God and whose avant-garde screeching on subjects like AIDS and schizophrenia frequently takes gothic into an area where it could scare bats. Her CV includes stints as a research scientist, prostitute and drug addict. Unsurprisingly, she isn’t normally seen in context. But then there aren’t many line-ups quite like Antony Hegerty’s 2012 Meltdown, where for a month dissident singers rub shoulders with twilight artists.

FRIDAY 27 JULY

Whatever happened to roughing it? Camp Bestival is, famously, more an upmarket middle England fete than a festival in the Hawkwind-play-Stonehenge sense but, still, why would anyone queue two and a half hours for the “Posh Wash” showers? Barring a below-waist hygiene disaster, surely Wet Wipes and water are sufficient for a weekend?

Iceland’s kings of heavy metal Momentum are launching into an assault called “The Creator of Malignign Metaphors”. It’s broad daylight and they’re playing about 10 meters from the kitchen window of a suburban-looking house. The stage is sited on an AstroTurf football pitch, with one of the goals pushed to the side of it. On the opposite side, kids are shimmying down a blow-up slide. Very little about G! conforms with the standard festival experience.

The UK premiere of Wynton Marsalis's Swing Symphony (Symphony No 3) last night was extraordinary on several counts. We heard, first and foremost, a real dialogue between jazz band and orchestra. Not one of those fist-bitingly cornball jazz arrangements where the jazz players get to stretch out and the orchestral players sit back and contribute the sustained, saccharine harmonies. This was a genuine coming together where all hands contributed equally to the rhythmic, harmonic and melodic detail of the work.

“It’s the oldest building in England,” Ana Matronic said breathlessly. “We’re probably going to behead someone.” The Tower of London is an unlikely venue for the fizzy pop monster that is Scissor Sisters, who dedicated one song to Anne Boleyn. In the end, no executions, or drawing or quartering, but they did have a couple of oversized beefeaters (pictured below) flanking the stage and dancing. Seeing them top the bill at the BT River of Music at the Americas Stage, you realise just how many pop classics they now have at their disposal from their four albums.

What function does a critic even serve at an event like this? Some of the best Colombian musicians across several generations are playing some of the best music Colombia has ever produced to an audience that largely consists of blissfully happy Colombians on Colombian Independence Day. But before the party got into its stride there’s a non-Colombian support band to consider. And consider them we must, because Ghanaian Afro-funk band Konkoma were as coolly polished and insidiously funky as the headline act.
