Operas have been written about many things -- magic flutes, tragic former courtesans expiring in their lovers' arms, or final battles with the gods -- but seldom about the trials and tribulations of corporate life.

This however is the theme of "Join!", with the script by a former top corporate executive, that has its world premiere on Wednesday in Vienna, a city better known for its more traditional operatic productions.

Michael Jackson's doctor Conrad Murray was clearly a "mismatch" unsuitable to care for the star on his doomed 2009 tour, with no expertise on drug addiction or insomnia, an expert witness said Tuesday.

Promoters AEG Live failed to spot a string of "red flags" that should have made them refuse to hire Murray, convicted of involuntary manslaughter in 2011 over Jackson's death, said cardiologist Daniel Wohlgelernter.

The lead singer of Grammy-nominated heavy metal band As I Lay Dying was arrested Tuesday in Southern California as authorities said he tried to hire an undercover detective to kill his estranged wife.

Australian actor Hugo Weaving, best known for his roles in "The Matrix" and "The Lord of the Rings", will head the jury for next month's Sydney Film Festival, organisers said Wednesday.

Justin Bieber is used to fans snapping his photo. Dubai police say he also triggered some speed cameras while driving a white Lamborghini during his stop in the Gulf city.

French actor Alain Delon will be honored at the Cannes film festival later this month with a screening of "Plein Soleil", Rene Clement's 1960 adaptation of "The Talented Mr Ripley", in which he starred.

The tribute will be paid to the 77-year-old Delon, who now lives in Switzerland, as part of the Cannes Classics series, festival organizers said Tuesday, confirming a newspaper report.

YouTube is proving to be a powerful launch pad for a new generation of Internet-savvy music stars from Psy to Macklemore and beyond.

The Google-owned video-sharing website has catapulted Psy, Macklemore, Justin Bieber and others onto global stages where they can cash in on digital downloads of songs; packed concerts; online ads, or even sponsored music videos.

Sweden's iconic disco group ABBA has no plan for a reunion, but a new Stockholm museum opening on Tuesday will offer the second-best opportunity to experience the foursome on stage.

"In the museum you can see us together again. That I think is the closest you could ever get," band member Bjoern Ulvaeus, a youthful-looking 68-year-old, joked in front of a group of reporters Monday.

Michael Jackson had levels of drugs in his body consistent with someone undergoing major surgery on the day he died in 2009, a coroner's expert said Monday.

The 50-year-old died from an overdose of the anesthetic propofol, given by his doctor Conrad Murray to help the singer with chronic insomnia during rehearsals for a doomed series of concerts in London.

A Bolivian brewer has come up with an innovative solution for quenching thirst and coping with altitude sickness: coca beer, based on the same leaf used to make cocaine.

Coca has only recently acquired its nefarious reputation: for millennia, people living along the Andes mountains have chewed coca leaves. The juice from the leaves has a mild stimulant effect, easing stomach pain and helping people from the lowlands cope with altitude sickness, known locally as soroche.
