🎃 SINISTER: A H.I.M HALLOWEEN HALLOWEEN FALLS ON A SATURDAY. WE’RE NOT WASTING IT. 😈 H.I.M Entertainment returns with SINISTER — our annual Halloween takeover, built for the people who want more than costumes and a crowded bar. This year, we’re going bigger: TWO ROOMS. TWO ENERGIES. ONE HALLOWEEN. Expect an open-format night with an Afro-Caribbean heartbeat — Hip-Hop, R&B, Dancehall, Afrobeats, Soca, Amapiano, Kompa, Caribbean classics, throwbacks and everything that makes the room move. 🎧 MUSIC BY: TK × FYAH TY (HTX) × IMPERIAL TK brings the uptown/open-format energy. Fyah Ty brings the island pressure straight from Houston. Imperial connects both worlds. One ticket gets you access to both rooms all night. Come spooky. Come sexy. Come creative. Just don’t come to stand around. 📍 HAVA NIGHTCLUB 246 Tremont Street, Boston, MA 📅 SATURDAY, OCTOBER 31, 2026 ⏰ 10PM–2AM 🔞 21+ | Valid ID Required 🎟 ENTRY 🩸 FIRST BLOOD The first release and the lowest price of the night. Once it’s gone, it’s gone. 👯 DOUBLE TROUBLE Grab your person. One ticket package admits two. 🕯️ THE COVEN Halloween is better with the crew. One package admits four. Later releases increase as the event gets closer. Waiting will cost you more. Costumes are strongly encouraged — and yes, we expect you to actually try. Last year, SINISTER packed the building. This year, Halloween lands on a Saturday and we’re giving you two rooms to get wicked in. UPTOWN ENERGY. ISLAND PRESSURE. AFTER DARK. This isn’t just another Halloween party. This is SINISTER. 😈🩸
