Although some people seem upset about the packed lineup, most Chicago electronic music fans are rallying around Saturday's DJ Surgeon show at the Logan Square Auditorium. For those of you unfamiliar with the music of Anthony Child, expect a dense mix of pseudo-industrial club tracks presented in an inimitable, forward-thinking fashion. Local DJs Gabe Palomo of Zuvuya and Frankie Vega of Blueline open the night. More info is, as always, available in Slowdown.
