Summertime roof concerts are in full swing at the Williamsburg club Output, and on July 1 Roy Ayers will once again be spreading his groovy, sunshine vibes at their Friday Night Live show. UPDATE: Sad to hear Roy is sick and won't be performing after all:

Due to illness, Roy Ayers is unable to perform at Friday Night Live on The Roof at Output this Friday 7/1. Tickets will be automatically refunded. We send our best wishes to Roy and hope he feels better soon. In his place, the Rinsed crew will bring their signature brand of house and techno to The Roof this Friday 7/1 featuring Dan Wender, Blacky II and Sophia MA. 5-10PM | NO COVER

Feel better, Roy. Another Friday Night Live show is happening tonight (6/24) with Amp Fiddle, DJ Amir-Bbe and DJ Reborn (tickets).
