Leonardo Rosado’s new track “Dreaming in Velvet” deserves its title, the nearly seven-minute drone composition a lush series of swells that is downright luxurious. Play it low as background music. Play it loud as sonic interior decorating — and exterior decorating, as well, the muted percussives seeming like storm noise heard at a distance. For a self-described drone, the music has a lot more going for it than just clusters of tattered sine waves. There’s field recordings and vocal incantations, paced in a manner that’s too unpredictable to ever be fully relaxing. Dense, rich material.
