Three Adelaide MP3s

Live, in performance, the Portland-based quintet Adelaide leavens its post-rock minimalism — all heady, light song form with a decidedly introspective bent — with 16mm films, giving the audience a series of dreamy visuals cues by which to follow the group’s non-verbal pop. If you can’t catch their current summer 2004 tour (more info at adelaidesound.com), you can download three tracks (with and without complementary visuals) from the band’s website. “Green Horizon” and “Bones of Things” are delightful, but it’s “Games Without End” that will entrance ambient/electronic fans, because it’s on that song that the digital nuances are most pronounced, notably a gentle surf of electric piano.
