Good Tuesday: eight things worth knowing about, six free or potentially free. Tonight’s best bet is Girl Ultra’s free small-room set at National Sawdust; uptown gets two museum and exhibition options, and the weekend queue is unusually strong for art, film, and Queens live music.

Harlem & Uptown

  • Lines of Survival: Living, Adapting, Imagining Tomorrow — on through Nov 1, daily 8am–4pm, The Africa Center, 1280 Fifth Ave at 109th St, free, no registration — five young African photographers document climate adaptation. It is walkable from Harlem.
  • He Built This City: Joe Macken’s Model — through Mon 10/12, Museum of the City of New York, 1220 Fifth Ave at 103rd St, open daily; NYC residents can pay what they wish — a handmade 50-by-27-foot model of New York containing hundreds of thousands of tiny structures, with binoculars provided for the details.

Live Music & Performance

  • Girl Ultra at National Sawdust — tonight 7–10pm, 80 N 6th St, Williamsburg, free with RSVP — Mexico City R&B and neo-soul in an intimate room, with complimentary cocktails. Check RSVP availability before traveling.
  • The Strokes + Beach House + TV on the Radio + Fcukers — Fri 10/2, doors 3pm / show 4pm, Flushing Meadows Corona Park, 16+, rain or shine — the official show still has limited paid tickets, but the r/LongIslandCity poster is offering one GA ticket free in exchange for company; use judgment with the stranger meetup. There is no event parking; take the 7 or LIRR to Mets–Willets Point. Official event details.

Art, Film & City Adventure

  • Artmageddon 2026 — rescheduled to Sun 10/4, 12–6pm, across Brooklyn, free community art walk — a storm moved the network of more than 500 artists, stoops, businesses, performances, and neighborhood “Art Villages” to this Sunday. The post highlights the newer PLG/Flatbush circuit.
  • Rooftop Treasure Hunt — starts Fri 10/2 at 6pm and runs through the weekend, citywide, ticketed; check the page for the current price — teams solve sequential puzzles tied to 30 years of Rooftop Films, visit NYC film locations in person, encounter filmmakers and live performances, and race for a $5,000 grand prize.

Food, Markets & Workshops

  • Free sourdough tasting at Dutch Kills CSA — today 3:30–7:30pm, outside Sac’s Place, 35-11 35th Ave, Astoria, free — fresh loaves, baguettes, and focaccia from Crescent Bakes; walk up if you are already near Astoria.
  • 4th Annual Mystic Mega Market — Sun 10/4, 1–6pm, 31st Avenue Open Street between 33rd and 35th Streets, Astoria, free admission — local mystical-art and food vendors, readers and healers, plus free workshops on candle magic, spiritual hygiene, tea blending, and tarot, an oracle-card table, and a supply swap.
