Juliana Koch has quietly moved from the Royal Danish Opera to the London Symphony Orchestra as principal oboe.

A prizewinner at the ARD International Music Competition 2017, she will share principal oboe duties with Olivier Stankiewicz.

She will also hold the title of professor of oboe at the Royal College of Music.

We published shocking testimony from Brazil last week about the San Paulo opera which has not paid some artists for three years.

This is not uncommon in South America and southern Europe.

Since then, we have heard that the Teatro Regio di Torino in Italy (pictured) is not paying some of its guest singers.

Other Italian houses are in a similar position.

If you have not been paid by a major opera house, please let us know.

We’ll compile a chart of stages to avoid.

UPDATE: Maggio Musicale in Florence, long in financial troubles, avoids paying artists if at all possible.

The young coloratura Emma Posman made an unscheduled national TV debut on Saturday night after Albina Shagimuratova called in sick three hours before curtain-up on Magic Flute.

Posman, 23 and unseen yet on any major stage, received a strong ovation as Queen of the Night. ORF reported 230,000 viewers for the relay.

It is reported in some print media that there was no other soprano in Mozart town that night who knew the role. Hard to believe.

The Greek composer has suffered a heart attack.

First reports say he is out of intensive care and recovering well.

Two months after the death of its founder and conductor Enoch zu Guttenberg, the Chorgemeinschaft Neubeuern has decided to disband.

Its final concert in September, a memorial for Guttenberg, will be conducted by Kent Nagano, Generalmusikdirector of the Hamburg State Opera.

The Mahler Chamber Orchestra has written individually to all players and staff who have worked with Daniele Gatti since 2010.

Citing his ‘firing from his position as Chief Conductor at Royal Concertgebouw Orchestra’, the MCO asks people to come forward with ‘any inappropriate or unacceptable situations’ that may have ever arisen.

UPDATE: Further to the leak of the letter MCO has issued the following public statement:

‘Daniele Gatti has held the Artistic Advisor title with the Mahler Chamber Orchestra since 2016. In our artistic partnership we collaborate in several periods of rehearsals and concerts each year. After the most recent information and developments regarding Daniele Gatti, we are closely reviewing the situation within our orchestra. As a democratic and collectively governed ensemble, it is important to us that all members are involved in discussing and evaluating the situation, which therefore can take some time.

‘As a free and independent orchestra that places a strong emphasis on the values of collaborative partnership and mutual respect, it is essential to us to maintain an environment in which all musicians, guest artists, staff members, and other partners feel safe and fully respected. The Mahler Chamber Orchestra does not tolerate sexual harassment or disrespectful behaviour in any form.’

Slipped Disc makes no presumption of guilt or innocence in respect of the Concertgebouw allegations.
