Turkish avant-garde electronic composer and producer Ilhan Mimaroglu passed away July 17. He was 86.

What I’ve heard of Mimaroglu’s music (admittedly, a small percentage of it) rivaled that of Iannis Xenakis for jagged, unpredictable dynamics, abrasive tonalities, and starkly menacing melodies. Besides his own challenging compositions, Mimaroglu worked on the soundtrack to Federico Fellini’s Satyricon and produced records for jazz musicians such as Charles Mingus and Freddie Hubbard, the latter of whose Sing Me a Song of Songmy (1971) was a harrowing, chaotic anti-war opus combining musique concrète, spoken word, and free jazz. Aside from Songmy, which turns up used vinyl bins with some regularity, the easiest place to access Mimaroglu's canon is the Agitation CD on Locust Records—or via YouTube, which has several quality clips.

RIP, Ilhan Mimaroglu.
