(Triple Door) The piano-bass-drum trio the Bad Plus includes some of the most masterly jazz musicians working today. Drummer Dave King, for example, is a phenomenon of fractal rhythm who can zoom in and out of a beat and keep it steady while disorienting and then reorienting the listener (and was the subject of recent documentary King for Two Days). For decades, jazz was about taking popular standards and fucking with them—Coltrane warping "My Favorite Things," etc.—but many contemporary jazz musicians have ossified into playing the standards of the mid-20th century. The Bad Plus twist our standards to their ends. Pianist Ethan Iverson begins their version of Black Sabbath's "Iron Man" with dissonant toy-piano tinkering, moves into a fragment of "Flight of the Bumblebee," then slams into the familiar riff before the whole group folds it into sonic origami. They also mess with pieces by Stravinsky, Pink Floyd, Nirvana, and Tears for Fears. And when they do play an old-fashioned standard, they absolutely torture it. (See their version of "My Funny Valentine.") Don't miss these guys.
