Eyal Netzer is a saxophonist and composer from Israel, a graduate of the Jerusalem Academy of Music and Dance and, separately, of a master's program in music therapy at the University of Haifa. He is a certified music therapist and teaches saxophone, improvisation and composition on the faculty of the Rimon School of Music's Akko campus. His route into the Tel Aviv free-jazz scene ran through the bassist Shay Hazan, whose quintet Netzer joined as tenor saxophonist. He first appears on record with that group on Good Morning Universe (NoBusiness Records NBEP 4), a 10-inch EP recorded at Levontin 7 in Tel Aviv on February 17, 2017 and released in an edition of 300 in 2018. The record is billed on Discogs to Hazan alone, with all four pieces his compositions, but its six-piece personnel puts Netzer on tenor saxophone alongside a second tenor player, Albert Beger, while the drum chair is split between Ofer Bymel and Haim E. Peskoff and Nadav Masel plays a five-stringed custom cello called the Hamsa. Netzer went on to record two further albums billed to the Shay Hazan Quintet, Domestic Peace (OutNow Recordings, recorded January 10, 2018 at Levontin 7) and Nuff Headlines (Chant Records, recorded December 18, 2019 at Haogen Studios), plus the 7-inch single "Beber's Cha Cha" (Jazz45, 2021, with UK phonographic distribution through Jazzman Records), and returned as a guest on Hazan's 2024 solo LP Wusul (Batov Records BTR088), playing tenor saxophone on eight of its ten tracks.

Netzer released his own debut as a leader in 2021: Speaking Through the Walls (Creative Sources Recordings, Lisbon), a duet with the veteran American-Israeli saxophonist and composer Stephen Horenstein, recorded live in Jerusalem in November 2017. The record pairs two tenor saxophones (Horenstein also plays soprano saxophone and drums) across eight pieces, three of them Netzer's own compositions, with Creative Sources founder Ernesto Rodrigues serving as executive producer. He followed it with Duo (2022), a studio session with the vibraphonist and marimba player Oded Geizhals recorded at Hateiva in Jaffa in October 2021; All About Jazz's review described the album as "a well crafted and attractive combination of straight-ahead balladeering and free-form improvisation by two masters of their instruments," built around Netzer's three-part "Sea Suite," inspired by scuba diving in the Mediterranean. His third leader date, Shine (2023), is a duo with the pianist Milton Michaeli, recorded at the Jerusalem Music Centre and opening with a three-part "Mamelodi Suite" drawn from South African township jazz, and closing on an electronic-tinged cover of Elton John's "Goodbye Yellow Brick Road." Shine's fourth track, "Evening Puja," is a Netzer composition he had already recorded once with the Hazan Quintet on Nuff Headlines (2021) and would record again, differently arranged, on Duo the previous year, one original theme carried across three separate projects over three years.

Falling Into Self (Pool Session) (2024) is a solo record, four long-form pieces on which Netzer plays saxophone and synthesizer over his own production, closer to ambient and minimalist electronic music than to a working band. His most ambitious work to date is Tèkès (2025), a roughly 45-minute suite for saxophone and an unusual string sextet of two violins, two cellos and two double basses, plus piano, percussion and flute, recorded at Hateiva and released in five parts titled for archetypal figures: "The Creator," "The Destroyer," "The Fool," "The Lover" and "The Seeker." Its personnel folds in several of Netzer's regular collaborators, with Shay Hazan on double bass, Milton Michaeli on keys and Oded Geizhals on percussion and flute. Haaretz called it in 2025 "an album soaked in emotion and beauty," and the critic Eyal Hareuveni, writing for Salt Peanuts, described it as "a patient, deeply emotional, contemplative, and mostly melancholic suite that captures the horrors of our time." Alongside his own catalogue, Netzer plays tenor saxophone in the Tel Aviv psychedelic-orchestral project Castle in Time Orchestra, appearing on its 32-piece 2024 release OTOTO (NaNa Disc) and its 2025 recording of Terry Riley's In C, and is a regular player with the Israeli Andalusian Orchestra Ashdod, an ensemble with its own history of touring the United States, Europe and Morocco. He has also played saxophone as a guest on more pop-oriented sessions, including a track on the singer-songwriter project YM's Dear God (2018) and two songs by the electronic project Amir Weiss & MEME (2023), and wrote and produced "Mala Mata (Seule Dans La Barque)" (2023), a French-language "lullaby for adults" sung by Camille Kravitzch. His own biography notes performances alongside touring American free-jazz figures David Murray and William Parker during their visits to Israel.

Netzer's saxophone voice sits close to the older generation of Israeli and American free-jazz players he has recorded alongside, favoring long, vocalized tones and a patient, unhurried sense of time over dense technical display; his own website quotes a 2025 Haaretz assessment calling him "one of the most creative wind-instrumentalists in local jazz." His writing draws as often on non-jazz material as on the tradition itself: Shine's opening suite is named for a South African township, Tèkès pairs saxophone with a chamber-scaled string sextet drawn partly from Arab-Andalusian training and partly from contemporary classical music, and his live work with the Israeli Andalusian Orchestra Ashdod and the electro-acoustic Castle in Time Orchestra runs well outside conventional jazz instrumentation. The duet format recurs across his output, first with the older reed player Stephen Horenstein, then with a vibraphonist and a pianist in turn, a pattern that reads as a musician working out his own voice one close dialogue at a time before scaling up to the string ensemble of Tèkès.
