As genre conventions continue to morph and blur, there's a wealth of stunning new music being made wherever groups of musicians have the imagination and ingenuity to transcend the old boundaries and just play whatever comes naturally. Sun Speak are such a group and their album Probiotic Orchestrations is full of music that's urgent, powerful, accessible and humorous, pulling together sounds and textures from the worlds of rock, jazz, electronica, Americana and the outer reaches of progressive music into compelling whole. Guitarist Matt Gold and drummer Nate Friedman first came together as Sun Speak ten years ago amid the white heat of the Chicago experimental scene, where they'd worked with such luminaries as Makaya McCraven and Patricia Barber.
