Manchester Collective is a new and enterprising group of musicians determined not just to create performances of high quality but to offer a new way in which the performances themselves are done. They started from scratch at the end of 2016, and I saw one of the first of their efforts, given at Islington Mill – a laid-back space in the basement of an old industrial building in Salford – in March last year.

Adam Gorb’s The Path to Heaven, with libretto by Ben Kaye, is his longest work to date (almost two hours’ running time without interval) and on a story that could hardly be more tragic – the Holocaust. Its premiere at the Royal Northern College of Music was conducted by Mark Heron and given by members of Psappha with singers and musicians from the RNCM, directed by Stefan Janski.

Striking it lucky with a successful new opera is a rare occurrence, though every company has a duty to keep on trying. The Royal Opera hit the jackpot with 4.48 Psychosis, a highly original approach to Sarah Kane's profound and authentic play by Philip Venables, the first Doctoral Composer-in-Residence on the scheme initiated by Covent Garden in alliance with the Guildhall School of Music and Drama. How could one not wish his successor, Israel-born Na'ama Zisser, all the best?

Ryuichi Sakamoto has conquered underground and mainstream with seeming ease over four decades, never dropping off in the quality of his releases. Indeed his most recent projects, following his return to public life after treatment for throat cancer in 2014-15, are among his best.

Sitting between the South Downs and the sea, Brighton’s borders are defined by nature. The Downs’ 2010 designation as a National Park also legislatively limits urban encroachment. The typically beautiful Sussex village of Falmer is on the city’s edge, supporting while doing its best to ignore two universities and a football stadium, with a pond and church at its theoretical heart but an A-road to London gouged through its middle, requiring a bridge between pond and pub.

This is the 50th Vale of Glamorgan Festival, and as its founder and director, John Metcalf, reminded us in a brief post-interval speech, he has been at all of them.

Depression, with or without psychotic episodes, is a rare subject for drama or music theatre - and with good reason: the sheer unrelenting monotony of anguish and self-absorption is hard to reproduce within a concentrated time-span.

Space is big – that seems to be the message of Unsuk Chin’s new oratorio Le Chant des Enfants des Étoiles. The work sets texts, ranging from the Baroque to the present day, concerned with space and scale. The work’s cosmic aspirations are reflected in its performing forces, a huge orchestra with augmented percussion, chorus, children's choir, and, for good measure, a suitably Gothic organ part.

Frederic Rzewski marked his 80th birthday with a visit to the Wigmore Hall, for the premiere of his aptly titled Ages.
