Thanks to Neil Feldman, who writes the Not Only Brooklyn, I  have the following info. I strongly urge you to sign up for his wonderful free newsletter about free cultural events in Brooklyn but not limited to Brooklyn.

Email Neil directly, with the message "Subscribe to NOB" and your first and last name, so it is legal for him to add you to the subscription list. And now, here’s what Neil has planned for you this Saturday.

You may see Neil at one of these events. He gets around on a bike and tries to make it to a lot of the things he’s so passionate about. This is just the tip of the iceberg when it comes to Neil’s newsletter.

At 4 p.m. on Saturday, Neil says Celebrate Brooklyn is the place to be when they celebrates the life and art of Ezra Jack Keats the prize winning artist and children’s books author and illustrator.

He is considered the first children’s author to place his diverse characters in urban environments, an unknowing pioneer of the multi-culturalism he saw growing up in Brooklyn decades before the concept had a name. He also used collage to illustrate his beautiful books. Performing in his honor are adults who understand children. Jamaican reggae and ska singer Rankin Don, who has come to Brooklyn and become Father Goose is perhaps the only children’s entertainer who uses the Caribbean musics. The Sippy Cups are California parents of pre-schoolers who have learned to entertain from their own children. Brooklyn singer-songwriter star Joan Osborne totally rocked out the Celebrate Brooklyn show she headlined last summer, but today she will read from Keats’s books between music sets, as will actor James McDaniel, probably best known for playing Lt. Arthur Fancy on NYPD Blue. Born in 1916 as Jacob Ezra Katz at 438 Vermont St in East New York, he felt compelled to legally change his name after serving in WW II due to the anti-Semitism he encountered in the publishing industry. FREE, but $3 at the gate keeps it great. Prospect Park Bandshell near 9th St & Prospect Park West.

From 5-11 p.m. follow Neil to the Brooklyn Museum’s Target First Saturday:

This is this month’s edition of the best, most heterogeneous FREE! party in NYC will have a distinct Caribbean accent, in honor of the annual world famous West Indian American Day Carnival on September 1, which will be sponsoring steel pan music, stilt walkers and more outside the Museum beginning at 3. Explore the weblinks for full details of the dance groups, film, author reading, gallery talks, Cuban film Life is to Whistle and outdoor dance party with Reggae Retro and Judah Tribe.

From 7 p.m. until midnight, Neil is off to Coney Island for some roller skating fun:

Dreamland Roller Rink celebrates its opening with a blow out party on wheels, with
DJ Julio, Gotham Girls Roller Derby, skate dancers, burlesque and more! You may recall NOB recommending the June fund raisers to help designer Lola Staar, who had a dream of transforming the former Childs Restaurant in Coney Island into a people’s rock rink. She did it!
$10, skate rentals $5. 3052 W 21st St on the Boardwalk.

And at 8 p.m. groove on over to Rooftop Films with Neil for some Home Movies:

Every year Rooftop hosts a program of Home Movies. Usually unfiltered, these films reveal feelings or fleeting incidents that might otherwise pass without thought, but when recorded can provide insights. This dozen films between one and 29 minutes long in this year’s program are different. They are less about the immediate moment than about the reflected moment—less web cam and more video diary.
