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”.

A few years ago I chanced upon something truly surreal. I was driving along a track in New Zealand. The way you do. There was a field on the left. In it there was a man sitting on a portable chair, a sketchpad in his lap, a pencil in his hand. Gathered in front of him, like a cluster of attentive disciples, was a tight semi-circle of cows. The man was wearing a black suit in a style popular at the end of the 19th century. The surreal bit is that, despite the grizzly beard, this was Columbo. None other than.

Mick Jagger is heading up a band named SuperHeavy. Also in on the project are Joss Stone, AR Rahman (composer of the Slumdog Millionaire soundtrack), Dave Stewart (the former Eurythmic) and Damian Marley. It seems outlandish and the product of an overheated PR person’s imagination, but many things in life can be both. Yet, this is real, not an April Fool-type joke.

It's not often that we in the critical world revisit a production towards the end of a run to see how it's settled. I had two reasons for wanting to return to Christopher Alden's English National Opera production of Britten's A Midsummer Night's Dream. First, I wanted to hear the liquid-gold countertenor of Iestyn Davies in action as Oberon, since he'd been voice-indisposed for one night only (and superbly doubled in that capacity by William Towers).

The Motown label will forever be identified with its Detroit birthplace, even though it had a Los Angeles office in the Sixties. The shift west was completed in 1972 when founder Berry Gordy Jr moved the whole concern to California. Before that though, in 1971, Gordy had launched subsidiary imprint Mowest to ostensibly showcase Los Angeles acts and as a test run for the California move. This gold-chip compilation shows Mowest is worth remembering. Motown's Mowest Story 1971-1973: Our Lives are Shaped by What we Love is the first comp to dig into this all but lost imprint.

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...

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

The Royal Opera House prides itself on knowing exactly who is registering on its mailing services, and just how high-class they are. Mr, Mrs, Ms, Miss, Dr, really can’t cover the possibilities. Hence the hilarity greeting their online registering process, which offers no fewer than 132 options for your title - which it is mandatory to fill in.

Sir John Tusa, chairman of theartsdesk, former managing director of the BBC World Service and Barbican Centre, has been made an Honorary Fellow of the Royal Academy today.

The other honoree is Joseph Rykwert, the art and architecture historian currently professor at the University of Pennsylvania.
