As if from an actual collection of blood relatives, the Schimscheimer Family Trio’s second album “Broken Home” opens a window into an alternate world—one in which songs become people, sounds describe stories, and music falls beyond categorization. The fake siblings (and their fake uncle) harness a mixture of woodwind, synthesizer, and percussion sounds in creating tuneful odes to their fake relatives, semi-traumatic childhood recollections, and intimidating animals of note.
