In January 2005, Dave Longstreth, the 23-year-old guitarist, singer and founder of the experimental rock band Dirty Projectors, wrote a letter to Don Henley, co-founder of The Eagles, expressing his admiration for Henley's 2003 appearance “testifying in front of the Senate against Clear Channel's homogenization of FM radio … I had already been thinking about the consolidation of information and power in the hands of a few self-interested corporations,” wrote Longstreth. “The transformation of the American landscape into a national grid of uniformly commercialized zones, each with its identical Applebee's, Wal-Mart and Blockbuster, has been deeply troubling to me. …” Longstreth added that Henley had inspired his new album/opera The Getty Address, which debuted that year as an above-ground underground masterwork of sorts. Well, five years later, The Getty Address gets another premiere in Dirty Projectors, Alarm Will Sound and the Los Angeles Philharmonic, a night of classical, experimental, rock and just plain over-the-edge, which journeys from the teasing charms of Ravel's Mother Goose Suite (a favorite, by the way, of Longstreth) to Philip Glass's Prelude from Akhnaten and Matt Marks's new live arrangement of The Getty Address with the acclaimed contemporary music ensemble Alarm Will Sound, conducted by artistic director Alan Person.
