Recent advancements in recording technology has made it easier than ever before for anyone with computer access to create and distribute their work from the comfort of home. Paradoxically, these advances also allow artists to hide themselves within their songs. There are countless effects and tools designed to manipulate (or replace) singing, to minimize the human voice. Tokyo's Elen Never Sleeps, the solo project of Hirotaka Kajiwara, has bucked this trend over the course of his young career, letting his voice — and all its charming imperfections — come through nice and clear. His latest EP, "Rum," is his most vocally daring to date, and his embrace of his own voice makes for an earnest and intriguing listen.
