For two days, Chandigarh thought out loud. Elsewhere’s Speaking Allowed turned the city into a room for ideas — sharp, unscripted, alive — carried by writers and artists who don’t trade in the obvious. On stage: JCB Prize winner Khalid Jawed, publisher Ravi Singh of Speaking Tiger, translator Arunava Sinha, the singer Rabbi Shergill, performance artist Inder Salim, the artist duo Thukral & Tagra, and authors Samina Mishra and Ita Mehrotra.
