This Sunday, Rock and Roll Playhouse will host a special Halloween-themed event at Brooklyn Bowl that will include a rare daytime Bowl Train DJ set from Questlove and a Grateful Dead set from Ross James & Friends featuring Nicki Bluhm.

The family-friendly concert will kick off at 11am with Questlove, and James, Bluhm, Alex Koford and Adam Roberts will take the stage at 3pm. There will also be a family costume contest at 3pm, with winners receiving tickets to Monday night’s sold-out Phil Lesh & The Terrapin Family Band Brooklyn Bowl show.

Proceeds from the event will be donated to the Jazz Foundation of America’s disaster relief program, which aims to help the families of musicians in Puerto Rico after the recent hurricanes that devastated the island.

Tickets for the event are available here.
