House music was still fueling the first wave of British raves when the Chosen Few DJ crew put on the first House Music Reunion Picnic. Now in its 20th year, the daylong event aims to capture the spirit and sound of an era widely considered house’s glory days; as the name suggests, the mood is more like a family reunion than a rave. Headliners and Chosen Few mainstays Jesse Saunders, Wayne Williams, and Tony Hatchett have been spinning records and producing tracks for three decades; they specialize in material that plays up house’s roots in soul and R & B, paying tribute to the disco styles that birthed the form as well as the diva-fied soulful house that helped break the style globally in the 90s. The lineup also includes special guest Rochelle Fleming, lead singer of Philly group First Choice. The House Music Reunion Picnic, held Sat 7/10 on the Jackson Park soccer fields at 63rd and Hayes Drive, runs from 8 AM until 8 PM, and gates (on Hayes) open at 6 AM. There’s an admission charge for the first time this year—$5 before noon and $10 after. Children under 12 are admitted free all day. Reentry is permitted with a wristband, and tents and grills are allowed on the festival grounds. True to house-music tradition, there will be a preparty Fri 7/9 at 9 PM at Green Dolphin Street (2200 N. Ashland) and an afterparty Sat 7/10 at 10 PM at the Basement (7600 S. Cottage Grove). Both feature sets by Chosen Few DJs, as well as by performers from further down the festival’s bill. For more information see the event’s Facebook page or chosenfewdjs.com.
