Ben Harper grew up in Australia before relocating to London. As well as making audio-visual installations, he has most recently been working as a composer with live electronic feedback (both analogue and digital), spoken word, and music designed for users of cochlear implants. His music, writing and visual art is based upon the conscious imitation of others to observe the nature of originality, and the removal of technique as a vehicle for musical expression. His public appearances have been rare, seldom venturing out of his bunker in East London, where he nurses his obscurity, mistaking it for genius. Over the past twenty years he has succumbed to pressure on a handful of occasions to present some of his music or artwork to the public in a small gallery or bar.

Gary David has led two lives simultaneously: musician and epistemologist. He was a professional jazz musician for 20 years. In the 60’s he formed a group called The Sound of Feeling, an innovative vocal-instrumental group. They recorded two albums for Verve, and Mercury records. Both won Grammy nominations. Studied pitch theory and practice with Erv Wilson from 1964 to 1995. Simultaneously, starting in 1964, Gary began his studies in epistemology, the theory of knowledge with J. Samuel Bois who was his mentor for the next 12 years. In 1975, he received a Ph.D. in epistemics. Since 1999, he has been engaged in a private counseling practice, as well as giving online seminars. called The Art of Learning with learning being the action by which we extend presence into the world. It has at its core his 40 year study of the biology of human emotion as the primary motivational system of the human being.

John H. Chalmers is a retired astrobiologist and prebiotic chemist from the University of California, San Diego. In addition to working in the fields of genetics, industrial microbiology, biochemistry and chemistry, he has had a long-term interest in microtonality and is the author of “Divisions of the Tetrachord,” a book inspired in part by Ervin Wilson’s work. Chalmers is also an actor with the Village Church Community Theater in Rancho Santa, California, where he resides, and has recently become a computer artist, having exhibited his music-theory generated polychrome plots in a number of venues in San Diego and one in San Francisco.

Grady works as the archivist of the works of musical theorist Erv Wilson and as the cultural liaison for Anaphoria Island. His own work involves using concepts of meta-culture realized in composing music for his instrumental ensembles in Just Intonation and special recurrent sequences. These are often combined with shadow theatre, installation and film. He prefers the term mesotonal (over microtonal) to further define a relation with theatrical anthropology and medical ethnomusicology .

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 forms — 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 and different cultural traditions.

Marcus Hobbs is a software developer focused on both creating software tools and using them to create visual and musical art. His first career was at Walt Disney Feature Animation whereas a digital artist he developed software used to create 3D artwork for Lion King, Pocahontas, Hercules, Atlantis, and Mickey’s Philharmagic, and Meet the Robinsons. He is currently developing mobile application software synthesizers that support microtonality, particularly focused on implementing the works of musical scale designer Erv Wilson. His iPhone and iPad application “Wilsonic” implements many of Wilson’s scale designs with interactive parameters so that musicians and composers can customize these designs to suit their values. He is a developer of “AudioKit Synth One”, a free open source additive software synthesizer which can import scales designed in Wilsonic.

Margo Schulter has been interested in European medieval, Renaissance, and Manneristic music since 1966; in 1998, John Chalmers of Xenharmonikon invited her to join the Alternate Tuning List, she saw Xenharmonikon 17, and was fascinated by what she read. In 2001-2002, she had the precious opportunity to collaborate with George Secor in an exploration of his 17-tone well-temperament of 1978; this process led her to explore Near Eastern music, as well as isoharmonic sonorities and Kathleen Schlesinger's superparticular melodic series. Jacky Ligon was a vital formative influence, and later Ozan Yarman and Jacques Dudon and Stephen Pohlit. She lives in Sacramento, California.

Paul Johnson (b. 1997) studied composition with David Vayo and Kyle Shaw, and has composed chamber pieces based on large-scale processes structured improvisation, and game rules. He holds a degree in mathematics and physics from Illinois Wesleyan University, and is interested in Erv Wilson's combinatorial and graph theoretic approaches toward tuning spaces. He is currently pursuing instrument building, and wants to use Harry Partch's "Corporiality" as a unifying concept for both popular and spectral composition.

Praveen S. Venkataramana considers himself a Wilsonian in approach and has composed a variety of chamber, solo, and electronic pieces in various tuning systems.
