The annual summer-solstice music festival is running right now across downtown San Jose and citywide neighborhoods — 218 performers, 53 venues, nothing costs anything.

Make Music San José is happening today, Sunday, June 21, spread across more than 53 venues throughout the city — parks, libraries, restaurant patios, a Willow Glen grocery store, a SoFA fermentation bar, the San Jose Museum of Art. The full bill runs to 218 artists. Every last bit of it is free, no RSVP required.

The event is part of Make Music Day, which lands simultaneously in more than 1,000 cities worldwide on the summer solstice each year — one of the few genuinely global participatory music events on the calendar.

The lineup at this scale is necessarily a sprawl, but a few things stand out. The Recycled Orchestra of Cateura — the Paraguayan ensemble that builds instruments from landfill waste (violins from oil drums, cellos from paint cans) and has toured internationally since their story went wide a decade ago — is on the bill. That's a legitimate headliner in any city. The San Jose Pop Up Choir is roaming the streets rather than staying fixed to a stage, which is either charming or chaotic depending on your tolerance for being surprised by a choral ensemble outside a taqueria. There's also a Roomful of Pianos session: if you play, you're invited to sit down. The Paseo de San Antonio corridor between 1st Street and Market runs as an open busking zone through 3rd and 4th — just walk it and see what you find.

The full schedule and interactive map are at makemusicday.org/sanjose, where you can filter by genre, venue, or time. Downtown locations are walkable from VTA light rail at Convention Center or Santa Clara station.

The move: Start on the Paseo de San Antonio busking corridor, drift to Hammer Theater Plaza, and if the Recycled Orchestra of Cateura is nearby on the map when you check — go there. Then let the choir find you.
