1950s recordings, mostly vocal, with wide range and variety — Alpine choral polyphony, poetic improvisation from Central Italy, funeral laments from the South, Sicilian songs to cure tarantula bites…

From the south-east corner, with uneasy Estonian identity, and ties to Russia via the Orthodox Church — striking singing about everything, in different lineups, with recordings from the 1930s till up to date.

Shashmaqom trio improvisation from Uzbekistan, artful and serious: heartfelt singing and fine tanbur lute playing, set off by the accompaniment of dutor and rabob lutes, and doyra percussion.

Deeply moving singing from Ferghana in Central Asia — classical, slow, suspenseful and meditative in a world of pain — accompanied by lutes, chang (a psaltery), nay flute, dayera tambourine, and ghijak spike fiddle.

From the north-eastern provinces, mixing Spanish, African and Guarani influences (and long derided for it), a distant cousin of tango. Guitar and six-string guitarron, accordion and bandoneon, double bass, singing.

Haydee Alba’s 1990 debut album — emotional and poetic from the off, already steeped in tradition — following the evolution of the form over its nineteen tracks. ‘An artist’s job is to make her public dream.’

The eighteenth-century poetry of Shah Abdul Latif Bhittai as celebrated nightly by waee faqirs, whose penetrating lutes and high whirling voices bridge musical and mystical experience.

Nusrat Fateh Ali Khan.

Refined, improvisatory, endangered traditional music for a quartet of two-stringed spike-fiddle, zither, two lutes.

‘Wild songs’ (without words), sophisticated choral singing, improvisations, pastorals and newer song forms.

Erik Marchand singing, with his accompanist Thierry Robin finding the ud better suited than guitar or mandolin to the intervalic arrangements of quarter tones peculiar to this repertoire.

Various songs — and valiha zither, made from a bamboo trunk, the sodina flute, the angorodao accordion, the kabosy lute, and the amponga tany, a ground zither made of plant rope, wood, and shit.

Fine singing and oud-playing, with zither and violin, and the percussion which characterises the hejaz style — nasgar and naqrazan, darbuka and tar, both held at the same time in the left hand, struck by the right.

Chimelougali is yodelling; luchenze is hooting whilst darting the tongue from side to side; kuama are trembling sounds, and rhythmic interjections. Including polyphonies, and a few with instruments.

The Theodore Vassilikos Ensemble powerfully performing Petros Bereketis — extended variations on eight modes —  the most important composer of the golden age of Byzantine music, an eastward Bach.

Stirring, beautiful historical recordings of paralogues — deep, traditional melodies — drawn from folklore, everyday life and classical mythology: solo voice, or choral, or with clarinet, ud, lyre, violins.

Wonderful, previously-unheard recordings by the legendary Bahamian guitarist, at his peak in 1965, made at his only New York concert, at home in Nassau, and in a Manhattan apartment. Gripping, one-off playing, continuously stepping out of line, or surprising you with accents, like Monk; rough, enraptured singing in the age-old tradition of local sponge fishermen, with startling irruptions of humming, babble and scat.
