This New York-based instrumental sextet is unlike your typical rock band. Experimental and percussive in approach, Blue Velvet’s image is organic and minimal: Their music has no vocals, no electric bass, no standard rock-drum kit and no loops or samples. Is it then worth listening to? Hell …Yeah! “Docile 1” and “Docile 2” from their EP Four Songs has a Hitchcock-style to it: strings cut harshly and are repetitive, producing a drony and eerie quality.
