The locals are understandably proud of Folkestone; Everywhere Means Something to Someone is an idiosyncratic guidebook offering an insider’s view of the town that bears witness to the depth of people’s attachment to it. Put together for the Folkestone Triennial by the artists’ collective Strange Cargo, this compendium of facts, memories and musings makes for compulsive reading.

This site has never acknowledged a distinction between high and popular culture. Nor, it seems, does the city of Birmingham. Currently bidding for UK City of Culture 2013, it is also promoting itself as the "Home of (Heavy) Metal". This summer, at various locations across the Black Country, a four-month festival looks at the likes of Ozzy Osbourne and celebrates the people who inspired him to “bark at the moon”.

While Michael Eavis’s fields were colonised by the solstice hordes, transforming a tranquil farmstead into a vibrant (and muddy) drop city, a very different and much smaller crowd assembled in the enchanting grounds of Dartington Hall in south Devon, for the second edition of Home, "a Festival with Acoustic Music at its Heart".

Spitalfields Summer Music Festival is now finished for another year, but bid farewell to its audiences in fitting style with We Are Shadows – a new community opera devised by composer John Barber and librettist Hazel Gould. Bringing together over 200 local participants, whether as singers and performers or working behind the scenes to usher this two-year project to fruition, it’s a show that celebrates not only the talents of the Spitalfields community, but also that most universal of London icons: the rat.

This is where the delirium kicks in. Tired but happy, the attendees started the third day of Sónar festival slightly boggled by how to pick and choose from the strange delights on offer. Saturday was when the true musical variety of the festival was displayed: straight-up hip hop to eye-popping South African tribal dance displays, balmy ambient revivalism to apocalyptic techno, heartbroken electronica to deranged prog rock: it was all on offer...

Montréal natives The Arcade Fire sing in English. Yet 65 percent of the Québec city’s population have French as their first language. Les FrancoFolies de Montréal is Francophone Canada’s annual celebration of non-Anglo Saxon music. This year, big draws include French visitors Jeanne Moreau and Etienne Daho performing Jean Genet’s Le condamné à mort with musical accompaniment. Local legend Jean-Pierre Ferland is reprising his seminal 1970 set Jaune, the first Québec album to - controversially - fuse Franco sensibilities with rock dynamics.

Everyone in the BBCSO is a potential soloist. I know this because the course I run at the City Literary Institute linked to the orchestra has welcomed principals, duos, two string quartets and three viola foursomes (proving that department the most individual, not the dense deserving butt of many a joke). I adore these players, but I love Erwin Stein's chamber arrangement of Mahler's Fourth Symphony even more, so this was bound to be a gem. Spitalfields' UK premiere of a recent song cycle by favoured Dutch composer Michel van der Aa could only come as an enterprising bonus.

Certainly a good cross-section of people were in attendance for the first day of Sónar.
