After failing to make the charts on its release 50 years ago this month, Astral Weeks has long since passed into pop mythology, its unique amalgam of jazz, folk and soul influences inspiring musicians, writers and filmmakers alike.

Many established artists, when out on tour, can get all a bit bashful about their new material. In fact, it’s not unusual for bands to hide a couple of new tunes in the middle of their live set with embarrassed mumbling about “you don’t really want to hear the new stuff anyway” before launching into a note-perfect rendition of a tune that was a hit several years previously.

Faithful Fairy Harmony is in the tradition of The Beatles’ White Album, Todd Rundgren’s A Wizard, a True Star and The Clash’s London Calling, all double albums because an outpouring of songs couldn’t be stemmed. Also like these, Josephine Foster’s 18-track double-set plays with listener expectations.

The road to full musical theatre production has been a long one for Hadestown. It began back in 2006, with Anaïs Mitchell’s song cycle – a folk/jazz take on the Orpheus and Eurydice myth – toured around Vermont in a school bus, then grew into an ecstatically received concept album in 2010, and has gone through further development with director Rachel Chavkin in Off-Broadway and Canadian stagings.

What adjectives best describe a performance of The Ballads of Child Migration? None of those you’d normally expect to see applied to an evening of superlative music-making, for the song cycle chronicles the deprivations suffered by child migrants sent from Britain over the course of one hundred years. Mostly they were sent to Australia, poor children in need of a loving home and an education who were used as slave farm labour.

What to make of The Simon & Garfunkel Story, which began a week-long residency at London’s Vaudeville Theatre last night and which tours in the new year? A success “from Sydney to Seattle” apparently, with Elaine Paige having called it “amazing” and various regional newspapers offering superlatives.

Josquin: Missa Gaudeamus, Missa L’ami Baudichon The Tallis Scholars/Peter Phillips (Gimell)

The young Dublin folk trio fuse vocal harmonies with superb acoustic musicianship, primarily on cello, fiddle and Nyckelharpa. They bring together Irish and Nordic – specifically Finnish – folk traditions, building them to dizzying heights on a foundation of acoustic drones and group interplay.
