Memorial Day weekend has become, ironically, equated with the kind of hard partying that leads to no memory at all come Monday (the actual holiday). This will surely be the case for revelers of these two Eastside-adjacent ragers this weekend. Friday, A Club Called Rhonda debuts Rhondavous, a bigger, badder, new gathering in a bigger space, with bigger spinners. Headlining the inaugural grinder, Belgian beatster Aeroplane, fresh off a crazed Coachella appearance, and the “legendary” Harvey (Sarcastic Disco). Boys in leotards, girls in not much else, all acting up and out on the dance floor make Rhonda one of the sexiest mixed-preference parties around, and this special event at Club 740 will surely bring it like never before. 740 Broadway, dwntwn.; Fri., May 28, rhondasays.net. Saturday, Hang the DJs gets hanged with special guest DJ Andy Butler (Hercules and Love Affair) plus Aaron Castle, Daisy O' Dell and Dan (Cosmic Kids) and others. Free Colt 45s until midnight and dancing till 4 a.m. make this a reliable holiday hoedown with the underground spirit of HTDJs' Echo Park house parties. Lacy Warehouse, 2662 Lacy St., L.A.; Sat., May 29, myspace.com/hangthedjs.
