All praise to the artist who can’t sit still. The best writers, painters, and musicians, the ones that define an age, are those whose work falls at crossroads: in conversation with the past, fully in the moment, and looking toward the future. The Horrors exploded onto the scene with a sound that was popular but fixated on the past, occasionally flirting with homage. But over the course of almost a decade and four albums, the English quintet have expanded their sonic field, drawing influence from a wider range of music while purposefully developing a sound all their own. Their new LP, Luminous, is their most mature and original offering yet. They’ve greatly expanded the scope of the traditional pop form, and their songs feel like compositions: rich, restless texts full of moving parts and shifting layers.
