Commissioned by the Chicago Cultural Center in 2005 to assemble a group representing the diversity of the city’s avant-garde, Mazurek began composing for what became his Exploding Star Orchestra (ESO). Including musicians from the often-segregated North, South, and West sides, ESO debuted in the urban epicenter of Chicago’s Millennium Park and, shortly after, recorded We Are All From Somewhere Else (Thrill Jockey, 2007). By the time of Galactic Parables Vol. 1, ESO’s 2015 triple LP on Cuneiform Records, Mazurek reflected to Pop Matters that “Exploding Star Orchestra is the conceptual, compositional and philosophical center of all my work... a life star of musical and visual and ideas."
