It's a good bet to expect the unexpected with Jim O'Rourke -- no matter which hat he's wearing (solo artist, bandmate, producer, remixer, etc.), each of the endlessly prolific projects that bears his name takes on a shape and identity all its own while retaining the originality and ingenuity that have become the hallmarks of his singular body of work. Eureka is perhaps his most stunning and surprising detour yet, a full-blown excursion into lush, melodic pop; granted, there's something inherently perverse about the very notion of O'Rourke and Chicago underground cronies like trombonist Jeb Bishop and cornetist Rob Mazurek tackling such classicist stuff, but instead the album is short on irony and long on affection -- in fact, its most subversive dimension is its very real mainstream appeal. -Jason Ankeny, All Music Guide
