North Hollywood duo Glow Marrow is Derek Coburn and Darin Green, two high school mates who released in early 2011 their debut EP Broadheart, which I guess, a posteriori, feels like something of a first draft. In just over a year and a half, the rough edges have been softened, polyrhythmic structures polished, and where instrumental layers would sometimes converse clumsily, they're now flirting at ease with one another. There you have it. Julian, first track off their upcoming follow-up Braver Days (out September 15th), a shimmering electro-pop song combining synth, guitar and a third of a drum kit with a touch of melancholy, and certainly the influence of Animal Collective's neo-psychedelia. Far more fluid thus far more gripping than its predecessors, it introduces the 'new and improved' Glow Marrow with which we'll be getting further acquainted as fall approaches. - Tracy Mamoun
