Chicago Reader music writer Peter Margasak as been coming on the show every third Friday of the month for more than two years now and his selections are as unpredictable as a Chicago spring. This month’s New Sounds segment is no exception; a cut from an Inuit artist. Also on the musical menu during tonight’s show: An Afro-Cuban take on a 1960’s pop hit, far out sounding Thai music and Brit electro freak folk.
