It's hard to figure out exactly where the baroque boom of 2006, spearheaded by Zach Condon's band Beirut, fits into today's indie rock landscape, which feels dominated by fuzzed out guitars, icy synths, and the blips and whirs of arcade machines. But judging by the 3,000-strong turnout at Manhattan's Terminal 5 on opening night of Beirut's first tour in four years, there's definitely room for brass and strings in 2011. The reason for this is simple: Condon and his band have never stagnated. It's easy to think of Beirut as the same weird group that played Balkan folk music on their debut, Gulag Orkestar, but they've actually kept growing, adding new (but old) sounds to the mix, like French or Mexican music from the early 20th century to this year's The Rip Tide. It's not just the influences that have changed, though. Condon evolved as both a songwriter and singer.
