Australian composer-performers Judith Hamann and James Rushford have worked together in countless projects for two decades, perhaps most notably in Golden Fur, their trio with Sam Dunscombe. Black Truffle is pleased to announce Midmeste, their first work as a duo. Its title is Middle English for ‘the middlemost point’, alluding to how the piece builds on the points of overlap between the highly personalised musical languages Hamann and Rushford have developed in recent years. Performed on cello and a variety of pipe organs, Midmeste is a spacious, sometimes unsettling exploration of their shared interest in alternative tunings, psychoacoustic phenomena, the physical properties of their instruments, and the usually peripheral sounds generated by the performing body.

Beginning with a sequence of austerely vibrato-less harmonics from Hamann's cello, trailed by Rushford's whistling portative organ tones, the music soon expands into a slow-moving melodic wander, pausing at times to linger over an uncomfortable harmony or particularly resonant cello tone. Hamann and Rushford have long histories of engagement with pre-Classical European musical traditions, having in past projects performed and radically extended the work of Solage, Louis Couperin, Johann Conrad Beissell and other composers. Here they use a 15th century song by John Dunstaple, ‘O rosa bella’, which returns throughout the piece, distorted, aerated and splayed into new forms.

Developed while the two shared residencies at Akademie Schloss Solitude, Stuttgart in 2020 and La Becque on Lake Geneva in 2023, Midmeste integrates recordings made (at at the invitation of the Biennale Son) on the organ of the Basilica St Valere in Sion, Switzerland—the world’s oldest playable organ, built in the early 15th century. Played by both Rushford and Hamann, the instrument’s idiosyncratic features, including bellows pumped manually using massive wooden beams, are integrated into the music through amplification. Creaks and thumps locate the music physically both in the performers’ bodies and the specific site of its making. Moving through a series of distinct episodes across its forty-minute span, Midmeste makes space for near-silent duets of high harmonics and hissing air, moments where twittering high tones and rumbling sub-bass could be electronic, and static fields that unexpectedly blossom into almost Romantic harmonies.

Listeners familiar with Hamann and Rushford’s work will find many familiar features here: the stunningly rich cello tones, their patient sustain allowing heightened awareness of the inner life of sound and its interactions with the environment; the care with which acoustic space is activated, becoming at times a third instrumental voice; the attention to fragile, unstable sonorities that sometimes have a comic edge. A major work from two key figures in contemporary experimental music, Midmeste synthesises rigorous exploration of fundamental questions of sound and performance with an unapologetic embrace of beauty.
