In the next few weeks the wider public will be introduced to the charms of Rolando Villazón (b. 1972). Anointed as a star of opera houses around the world in the last decade, the Mexican tenor is about to participate in ITV1's Popstar to Opera Star. As singing celebs from the world of pop music take on the big arias, Villazón has been cast as mentor, panellist and figleaf. It is all a very long way from Covent Garden.

The singer Lhasa de Sela passed away from breast cancer in her Montreal home on 1 January just before midnight, at the age of 37. Since this news emerged my email box has had numerous messages about this tragic loss, including from theartsdesk critic Robert Sandall who wrote about her “extraordinary talent, amazing life… a total original, a real artist”, and adds a note below this article. Howard Male said, “The Living Road is one of the truly great albums in any genre, in my opinion.”  While never forming a conventional career, her three albums La Llorona, The Living Road and the self-titled Lhasa managed to sell more than a million copies between them.

Tonight, 23 December, is a significant night for culture in Oaxaca, Mexico – it’s the Noche de Rabanos. The Night of the Radishes.

How old Placido Domingo? Old Placido Domingo in not bad vocal health, to paraphrase Cary Grant's celebrated telegram reply. The other answer depends on your source of reference. Domingo is 68 in the eyes of last night's rather lazy, over-reverent Imagine, but 75 according to my not so New Everyman Dictionary of Music. Where did that come from? It would make him an octogenarian by the time of the date he proudly announced at the programme's end as the furthest-forward in his singer's diary. Perhaps this isn't that much of an issue.

History is written in blood, however elegant the cover. Nowhere is this more apparent than in the collapse in 1521 of the Aztec Empire, a culture that presented Europe with a vision of such otherness that it could only be destroyed. In 2002, the Royal Academy of Arts tried to persuade us to look beyond the grisly tales of human sacrifice to a more nuanced portrait of a people steeped in gory rituals that we, soaked in the serial-killer television porn of the 21st century, might strangely understand.

To mark the release of Tom Russell's superb new album Blood and Candle Smoke this week,  the cowboy singer-songwriter reports on his trip earlier this month to the Mexican city of Juarez, one of the most dangerous cities in the world, just over the border from where he lives in El Paso, Texas.

"Down below El Paso lies Juarez, / Mexico is different, like the travel poster says…"
