The King Kong musical about to scale Melbourne like the Empire State Building might have a soundtrack loaded with laudable names from electronic music, but it's still, y'know, a musical. A three-minute teaser for the show's music offers sneak peeks at Justice's characteristically filter-disco "The Greatest Show on Earth," 3-D from Massive Attack's characteristically spooky-cinematic "Colossus" and (with Guy Garvey from Elbow) "In the Face of Forever," and, hey, Sarah McLachlan's characteristically Sarah McLachlan-y "What's It Gonna Take?" The biggest draw, though, is a new track from the Avalanches, who shared a mixtape last year but haven't released an album since 2000's landscape-shifting Since I Left You. The Aussie group's "Get Happy," a digital-funk take on an old popular standard, while promising, is hardly the full-fledged sequel fans have been awaiting. With the narrative exigency and dramatic vocal styles of musical theater, the music sounds like it's best judged as just that: musical theater. We'd still happily fly Down Under to take in the show.
