Visiting from Japan, violinist CHIKO performs a set of 20th century classics: Morton Feldman's for aaron copland; Toru Takemitsu's Distance de Fee; Igor Stravinsky's Elegy; Astor Piazolla's Ave Maria; and Ennio Morricone's Love Theme from Cinema Paradiso. She will joined by HADLEY MCCARROLL on piano.

Improvisations by LORIN BENEDICT and RON HEGLIN - Two vocalists, improvising together, each of whom sings in his own invented language.

Closing the concert, THE MOSSWOOD IMPROVISATION GROUP, a collection of local improvising musicians, will perform a set of free improvisation. Performers include: TIM PERKIS, electronics; KANOKO NISHI-SMITH, koto; BRENDAN LAI-TONG, trombone; MATT INGALLS, clarinets; TOM DJLL, trumpet; BEN DAVIS, cello; KEVIN CORCORAN, percussion/electronics; KEVIN CK LO, violin/flute/piano/electronics.

CHIKO is currently one of 1st violin players of the City of Kyoto Symphony Orchestra. In addition to the orchestra, she promotes and plays her own concerts including solo, duets and chamber music. She also works on collaborative creations between violin and various artists in other fields. With the theme of “awakening of the five senses” with her “sound” as the starting point, she incorporates improvisation and creates a unique world view through her variety of music. She studied mental coaching and Ericsson Hypnosis, and adopted a spiritual approach to help the sound and music reach deeper into the human heart. Recently she has started doing sound healing in private sessions.

RON HEGLIN is a trombonist and vocalist working with extended technique on the trombone and with spoken and sung imaginary languages as a vocalist. His vocal music has been influenced by his study of North Indian vocal music. He works both compositionally and in an improvisational mode and is a member of the Bay Area music context as well as performing internationally. He is a founding member of the groups MUSIC FOR ALL OCCASIONS, ROTODOTI, and BRASSIOSAURUS, and has performed with the Merce Cunningham Dance Company, Leo Smith, Henry Brant, Logos Duo, Tim Perkis, John Bischoff, Tom Djll, and Toyoji Tomita.

LORIN BENEDICT is an improvising vocalist (scat singer, essentially) who works in the areas of jazz and related music. He co-leads several small groups dedicated to playing highly structured music in a manifestly loose and playful way. This includes the duo Bleeding Vector, the trio The Holly Martins, and duo projects with drummer Sam Ospovat and bass player Logan Kane, respectively. He has also, over the past two decades, appeared as a side-man in groups led by musicians such as Howard Wiley and Sheldon Brown, among many others.

a tribute to TOM NUNN with GHOST IN THE HOUSE and friends

TOM NUNN was a free spirit dedicated to practice and discipline. He could play for hours on any of his invented instruments with any other musician. Regardless of his intuitive approach to improvisation, his musical success was grounded in a solid technical mastery of his instruments. – Ed Herrmann

Extreme sounds / extreme emotions. DEL SOL STRING QUARTET finds the range of expressivity through the exploration of sound, noise, silence, and musical restrictions. Featuring the music of composers

Fascinated by the feedback loop between social change, technology, and artistic innovation, the San Francisco-based DEL SOL STRING QUARTET is a leading force in 21st-century chamber music. They believe that live music can, and should, happen anywhere – whether introducing Ben Johnston’s microtonal Americana at the Library of Congress or in a canyon cave, taking Aeryn Santillan’s gun-violence memorial to the streets of the Mission District, or collaborating with Huang Ruo and the anonymous Chinese poets who carved their words into the walls of the Angel Island Immigration Station.

Since 1992, Del Sol has commissioned or premiered thousands of works by composers including Terry Riley, Gabriela Lena Frank, Tania León, Frederic Rzewski, Vijay Iyer, Mason Bates, Michael Harrison, Huang Ruo, Pamela Z, Chinary Ung, Chen Yi, Erberk Eryilmaz, Theresa Wong, Reza Vali, and Kui Dong. The quartet regularly works with composers through workshops, universities, as well as Del Sol commissioning and incubator programs. They especially value their ongoing relationship with the Gabriela Lena Frank Creative Academy of Music in Boonville, CA.

Del Sol’s eleventh album "A Dust in Time" debuted at #3 on Billboard in October 2021. Called “excavations of beauty from the elemental” (NY Times), this hour-long meditation was released in the form of a coloring book. Their previous album “Kooch-e Khamân” (February 2021) features 7 new works by young Iranian composers and charted #5 on Billboard. In the 2021-2022 season, Del Sol continues its Joy Project, performing outdoor pop-ups around the Bay Area of music written to inspire joy. They also are producing two large projects: “The Angel Island Project,” an immigration-themed oratorio by Chinese American composer Huang Ruo, and “Between Worlds of Sound,” a collaboration with North Indian musicians Alam Khan & Arjun Verma. In 2021, the quartet were featured artists at the Venice Bienalle’s Arts Letter and Numbers Pavilion. They are current artists on the ImmerSphere roster, a groundbreaking platform that produces performances in augmented reality.


Our focus is on the bay area experimental and new music community, hopefully encouraging crossover among sub-scenes (composition and improvisation; established and emerging; institutional and underground; etc.) We strongly suggest local musicians attend concerts before requesting to perform on the series. Visting artists aritsts are also welcome, ideally splitting a concert with local musicians.

There is a "hall-like" reverberation in the space, so until we have a better feel for the limits of the space, we are only programming mostly acoustic performances, but we will also consider lightly amplified electronics.

50% of ticket sales is given to the performers.
