(Crocodile, 8 pm, $15, 21+.) Prefuse 73 was once the golden boy of IDM/radical instrumental hiphop—until Flying Lotus barged in and swiped most of his glory. Prefuse (Guillermo Scott Herren) has been relatively quiet lately; his last album, The Only She Chapters, came out in 2011. That work found him retreating from his trademark hyper-rhythmic disjunctions and plying a more melodic approach, bolstered by several collabs with female vocalists (the late Trish Keenan, Zola Jesus, Niki Randa, etc.). It's kind of a lost gem in Prefuse's catalog, which spikes with some of the most intoxicating mutations of hiphop by an American producer from the last decade. His ability to translate his baffling beat science on record to the live stage has been inconsistent; the best Prefuse shows I've seen have happened when he brings a full band. Fingers crossed. [Since this preview went to press, we've learned that Prefuse will be playing solo.] With Theoretics and IG88.
