It’s been nearly a decade since the last proper full-length by the Japanese musician Cornelius, also known as Keigo Oyamada. Like his American counterpart Beck, Oyamada spent the ‘90s dispensing pitch-perfect pastiche-pop before veering off into numerous other projects. Unlike Beck, Cornelius hasn’t returned to ground yet, and his latest, Constellations Of Music, is a compilation of Oyamada’s recent production and remix work, alongside three brand new Cornelius tracks. Also unlike Beck, Oyamada has continued to seek the further-out. The arrangement on Plastic Sex’s “The End” is unmistakably Cornelius, a crashing sci-fi melange of layered space-funk and rhythmic pop-noise that gets weirder as the Devo-like pop song progresses. The album-opening “Escalator Step,” by the ex-Buffalo Daughter bassist Yumiko Ohno, is all happy futurism and ineffable melodic turns imported directly from the post-war space age, with their own shades and cues for Japanese musicians and audiences. In a similar vein, the most beautiful track is the swaying “May You Always,” by salyu x salyu, for whom Oyamada also produced and arranged 2011’s s(o)un(d)beams. Here, he reaches into a half-remembered Shibuya-kei dream of Hawaiian exotica and mid-century American pop to create what sounds almost like a standard. The trio of new Cornelius originals pushes further into the lite neon landscapes and electroacoustic bleep jazz of 2006’s Sensuous, now with skittering steel drums (“Holiday Hymn”) and the promise of futures even Cornelius hasn’t fully grasped yet.
