Main Source, the veteran hip hop crew who counted Large Professor as a member and were responsible for releasing Nas' first-recorded verse ("Live at the BBQ"), reissued their 1991 debut Breaking Atoms earlier this year and reunited for their first show in over a decade at SOB's in February. They've now added another reunion show.

This one's a free SummerStage show opening for the legendary George Clinton & Parliament-Funkadelic on June 11 in Flushing-Meadows Corona Park in Queens. Also on the bill is old school Queensbridge DJ Marley Marl. The show goes from 5-8 PM, and it'll be hosted by Marley Marl's Queensbridge neighbor (and fellow Juice Crew member) Roxanne Shante.

Large Professor has another free SummerStage show in Queensbridge Park on July 14 opening for Queens vet (and Lost Boyz member) Mr. Cheeks. That show goes from 7-9 PM.

George Clinton tours a lot (we caught him in Chicago in February), and last year he signed to Flying Lotus' Brainfeeder label.

There's so much more old school and golden age rap on this year's SummerStage schedule, including Digable Planets, KRS-One, DJ Premier, Slick Rick, Capone-N-Noreaga, GZA, Camp Lo, Kid Capri, Jadakiss, MC Lyte as part of the “Rock Steady Crew 40th Anniversary” and more. Check out the full SummerStage schedule HERE.
