Katara Multi-Purpose Hall

This guide to Katara's amphitheatre in Doha opens on its very first night, in December 2011, when composer Vangelis was given free rein to design an entire evening of music for the venue's debut — and when, partway through his performance, part of the audience began quietly leaving. You'll hear about the five-movement piece he built around the myth of Orpheus, the five hundred performers sharing the stage, and the guest list that included Jeremy Irons and Angela Gheorghiu. Stand back from the water to take in the full sweep of the tiered seating cut into the hillside.
