Lewis Patzner conducts the string orchestra; Omid Zoufonoun is youth orchestra director, not a guessed co-conductor. Free public youth-orchestra admission. One individually reviewed public physical classical performance in the 2026–2027 edition. Exact current primary identity/full date/main clock/physical venue required; no guessed end, unnamed cast, biography repertoire, private activity or virtual duplicate. New seasons, changed native IDs and moved performances require continuity review; a missing listing is not cancellation. Oakland venues are independently corroborated by the presenter’s linked venue pages; Valley Center is at former Holy Names University, not Castro Valley. Excludes San Ramon/Livermore touring dates and unreviewed Quincy Jones tribute. No private student roster is collected.
