"Canadian composer of Ukrainian descent Marc Sabat (*1965) has been based in Berlin since 1999. He makes pieces for concert and installation settings, drawing inspiration from investigations of the sounding and perception of Just Intonation and of various music traditions - folk, experimental and classical. He is a frequent collaborator, seeking fruitful interactions with other musicians and artists of visual and literary modes to find points of shared exploration and dialogue between various forms of experience. Sabat studied composition, violin and mathematics at the University of Toronto, at the Juilliard School in New York, and at McGill University, as well as working privately with Malcolm Goldstein, James Tenney and Walter Zimmermann. Together with Wolfgang von Schweinitz he has developed the Extended Helmholtz-Ellis JI Pitch Notation and is a pioneer of music written and performed in microtonal Just Intonation. He teaches composition and the theory and practice of intonation at the Universität der Künste Berlin. Scores and artist editions are available under a creative commons share-alike non-commercial license through Plainsound Music Edition."

Rebecca Lane is a flute and bass flute performer from Melbourne who is currently based in Berlin.

Fredrik Rasten, guitarist / improviser / composer "I am a Norwegian guitarist (b. 1988) working in the field of experimental music, both improvised and composed. My main focuses are exploring and utilizing the acoustic possibilities of the steel string guitar, motivated by a fascination for the almost tactile experiences of acoustic phenomena. The last months I have been working extensively with intonation, with an extended concept of consonance as a point of departure, both in solo work and in duos with trumpeter Torstein Lavik Larsen and bass player Jonathan Heilbron. I have also had the lucky opportunity to take lessons in this field with composer and violist Catherine Lamb.

Other music that I am inspired by includes wandelweiser music, traditional british folk and early music."

"Fredrik Rasten works with acoustic guitar and in exploring the possibilities for putting this instrument in new musical contexts. With extensive use of preparations and different non-tempered tunings, he creates warm sounds in gradual development. He also includes subtle use of the voice to make interfering thick timbres and tonalities in combination with the guitar. A goal for the music is to open a room for details that invites the listener inside the musical material in an active and exploring way.

He is also playing composed music, especially related to quiet / Wandelweiser music and Just Intonation music, and has performed pieces by Johan Lindvall, Antoine Beuger and Catherine Lamb."

"Following interacting points within expanding harmonic space, Catherine Lamb has devoted her structural work to the inner life of tonality, constantly searching through the limits of human perceptions and resonances in overlaying atmospheres.

Lamb's continued series Prisma Interius (2016-ongoing), made with her partner and frequent collaborator Bryan Eubanks, filters the outside environment into a harmonic field, basso continuo, tanpura, or bridge between the musical form and the perceptual listening space. Her first orchestral work, Portions Transparent/Opaque (2014), was premiered by the BBC Scottish Symphony Orchestra at the 2014 Tectonics Festival in Glasgow, Scotland. After an extended tour of her solo work Shade/Gradient (2012) through North America in 2012, Lamb received a travel grant from the Henry Cowell Foundation, allowing her to pursue work with Eliane Radigue and to form new relationships with European musicians.Earlier in her career, Lamb studied under composers James Tenney and Michael Pisaro at the California Institute of the Arts, where she also met director and dhrupadi Mani Kaul. It was during this time that she began diving deeply into her own practice of what she later termed "the interaction of tone."

Lamb is the co-founder of Singing by Numbers (2009-11), an experimental vocal ensemble formed with Laura Steenberge that focused on pedagogical research around pure ratio tuning. She has written for ensembles such as Ensemble Dedalus, Konzert Minimal, the London Contemporary Orchestra, NeoN, Plus/Minus, and Yarn/Wire. Lamb is involved in ongoing research with Marc Sabat on intonation; with Johnny Chang on Viola Torros; develops work regularly with musicians such as Rebecca Lane, Dafne Vincente-Sandova, and Frank Reinecke; as well as taking part in Triangulum with Julia Holter and Laura Steenberge.

Lamb is the recipient of a fellowship from Akademie Schloss Solitude (2016); an Emerging Composers Grant from the Wallace Alexander Gerbode and William and Flora Hewlett Foundations (2008-09); and was a Staubach Fellow at the International Summer Course for New Music in Darmstadt, Germany (2016). Lamb's writings and recordings have been published by another timbre, Black Pollen Press, Kunst Musik, NEOS, THE OPEN SPACE Magazine, Q-O2, sacred realism, and winds measure recordings.She received a B.M. from California Institute of the Arts, and an M.F.A. in music/sound from Bard College."

"Yannick Guédon is a French born composer, singer and performance artist, currently living in Brussels.His work focuses on tiny variations of timbres, the inner pulsation sensations and subjective notions of time, silence and error. He pays particular attention to the place and context in which each musical situation is displayed.

In 2006 he wrote his first piece, pitulatif, for a solo voice. He followed it with ticdê (2007) a vocal trio, infimie (2007)for voice, electroacoustic, video and light, soupir (2009) and pause (2010), for clarinet, guitar, percussion, cello and voice.In 2011 he initiated the cycle of situations a _ t e m p _ s, which generates:
