Now in its 10th year, the Crotona Park Jams series brings together some of the city's most iconic beatmakers for a weekly summer throwback party in Crotona Park. The goal, say organizers, is "to recreate the classic hip-hop park jams of the 70s and early 80s."

The free series is hosted by GrandMaster Caz and will feature deejays Biz Markie, Cash Money, Kool DJ Red Alert and Afrika Bambaataa, among others. The events are family friendly, with alcohol and filming prohibited.

And, sorry aspiring scratchers, the promoters warn: "Legends & Pioneers Only on the turntables."
