“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.

Peter Sellars has a talent for controversy, from his early days when he was the director who brought you Così fan tutte set in a diner on Cape Cod, Don Giovanni as a cocaine-snorting, Big Mac-eating slum thug, and Figaro getting married in Trump Tower. At his best, in John Adams's Nixon in China, Saariaho’s L’amour du loin, or his Teodora at Glyndebourne, the results have been some of the freshest and most inspiring stagings of new music seen in recent times.

The omens did not augur well for this one. Under The Bridge, a venue beneath Chelsea Football Stadium, used to be an iffy nightclub called Purple but has been redesigned by the man behind America’s House of Blues chain into a shiny visual fusion of TGI Friday's and the Hard Rock Café. Industrial girders are visible in the ceiling and the walls are plastered in top-notch rock and pop photography but, overall, there’s an ersatz, squeaky-clean vibe that’s going to take some piercing by any act who takes the stage.

Madonna earned her place in the pop elite many years ago, and there are many reasons for this, which needn't be reduced into a list. Certainly though, a big reason will be the obvious - how much better her fans' lives are with her songs in them.

Paloma Faith has always struck me as a few cuts above your average conveyor belt post-Winehouse soul sister. A recent appearance on The Graham Norton Show in which she gave Russell Brand as good as she got in the verbals department suggests that there's more to this former magician's assistant than meets the eye. And 15 minutes into last night's gig, the first of her two shows as part of Somerset House's Summer Series, she firmed up her gobby intellectual credibility by name-dropping lefty post-Structuralists Gilles Deleuze and Félix Guattari.

In the grim windowless warehouse that is the Village Underground, Eighties hip-hop-pop princess Neneh Cherry told us that her current return to all things jazzy and experiment was born just down the road in Acton. This is only interesting in the sense that her three collaborators, The Thing, actually come from Sweden where Cherry herself is also based.

It is sometimes hard to be enthused by midweek gigs. Last night was one of those occasions, at least for the 30 seconds I thought I was going to be watching most of the show on the iPhone screen of the six feet of beard that planked itself in front of me just in time for the music starting. Those are the nights you need, as Sharon van Etten might say, “something that’s hard to describe”. Something that changes your mood, and makes you smile, and doesn’t happen all of the time. Something fun.
