This is an amazing album. I'm almost done listening to it straight through twice. I think Pitchfork was pretty competent with their review of it, so I'm going to steal some excerpts:
Maybe no one told Clap Your Hands Say Yeah that first impressions are important. Or maybe they've just got massive sack. Either way, their self-released, self-titled debut CD opens with the weirdest, most potentially grating bit of snake-oil salesmanship you're likely to hear until Tom Waits puts out another record. I happen to dig the song, entitled "Clap Your Hands!" (a theme is emerging), but a maniacal carny barking over a stuttering calliope isn't for everyone. Those who persevere, though, will quickly discover that this garish foyer gives out onto spacious, elegant chambers of clean lines and soft lights.
The record is consistently, remarkably strong, but "The Skin of My Yellow Country Teeth" in particular stands out, with its richly buzzing synth phrases, textbook Modest Mouse guitar lead (a trebly, gliding string bend skimming over the rhythm like a flat stone over a pond), contrapuntal bass, and shuffling drums. The song also features one of vocalist Alec Ounsworth's most memorable performances: He ramps up the urgency as the heavier chords kick in, his voice cracking and shifting in cascading waves as if someone were pressing his vocal cords to a fret board and bending them. "Is This Love?", with its clean, galloping guitars and fruit loop synth trills is the song most blatantly redolent of Neutral Milk Hotel (especially of the unhinged pop and careening vocals Mangum favored on On Avery Island), and its dizzily wowing vocal harmonies carry over to "Heavy Metal", where fuzzed-out bass and wheezing harmonica punch smart shapes into the fizzy guitars.
