# OpenConcert

An open registry of live music — community orchestras, ensembles, and beyond.
Built so anyone (and any AI assistant) can answer "what's on near me?" or
"what has this orchestra played in the past?" without scraping bespoke
websites. The feel is open music making, not elite gatekeeping.
