Though the Montreal quintet features members of such well established groups like Le Fly Pan Am, Shalabi Effect, and A Silver Mt. Zion, this is hardly a stepping stone for the band. Instead of falling back on those groups' varied approaches, Et Sans mines the realm of the late 1960s and 1970s, touching on Suicide’s keyboard vamps, Kraut Rock, psychedelia, and baroque pop. The first track, “Lachose Nue Nue Nue Ou l'Amoncellement Spectral du Mac,” begins with slowly percolating beats, with distant murmuring voices and washes of ambient static. The 18 plus minute centerpiece “Une Bouche Végétale, Des Creatures Soufflent des Sécrétions du Tout Fout l” follows and immediately dispels the eerie calm established by the last song. Over an unrelenting Farfisa, manipulated vocals, shrieking electronics, and pounding drum, the song reaches its noisy zenith until slowly fading out to just a groaning keyboard and a drum and handclap providing the rhythm at about the seven minute mark. As the track progresses, it slowly begins to pick up the pace, until it has regained the tempo it utilized in its first section. Whereas earlier the vocals were hidden behind a gauze of electronic manipulation, they are more prominent here, with the lead voice intoning mantra like verses while backing vocals provide cheerful “bah, bah, bah’s.” The song in many ways resembles early New York keyboard noise mongers Suicide, but also draws comparison to Stereolab in its extended length, and sublime pop frenzy. “Made Moiselle Ogive, Un Tremblement Osseux Dans Lederriére” manages to match the intensity of the previous song through the usage of one percussive piano chord which provides the rhythm for much of the song. The delicate sense of urgency is increased by more classical instrumentation, such as a harp, backing strings and hushed vocals, all of which infuses the song with a beautiful haunting quality. The final track is perhaps Et Sans most accessible. “Les Courbes Sanglantes Entendues de l'Organe Trop Uraíment Halluciné” is built on Felix Morel’s capable drumming, which drives the song over its 11 minute course through a panoply of keyboard, breathy vocals, and squirming electronics. While some may balk at their length and unwavering rhythm, they are really missing the point. Par Noussss Touss les Trous de Vos Crânes! is an album that manages to skillfully balance Et Sans predilection for the experimental and the accessible, making for a challenging and infinitely rewarding listen.
