Pencil This In

EVENT: Lily Koppel, author of the Red Leather Diary, is celebrating the paperback release of her book tonight. Koppel talked to us last year about the 77-year-old old diary she found in a dumpster on Riverside Drive belonging to Florence Wolfson. Tickets include a slow gin fizz, as a nod to the flapper era that the book takes place in, and a sneak preview of the upcoming theatrical adaptation. More details here.

MUSIC: The headliner alone is worth heading to Bowery Ballroom for tonight. Regina Spektor will be in the spotlight once again tonight for a Planned Parenthood Benefit, which also features performances by Ra Ra Riot and The Bloodsugars.

7 p.m. // Bowery Ballroom [6 Delancey St] // $35

THEATER: Loosely adapted from the acclaimed dance/theater play by Mikuni Yanaihara, The Blue Bird is the latest febrile performance art mash-up from the Witness Relocation dance/theater company. They say their new show concerns "crossbreeding humans with insects, technology, the dangers of leaving your mouth hanging open, and maybe losing the ability to look up at the sky." Claudia La Rocco at the Times declined the free beer offered at recent performance, which might explain her somewhat muted praise: "From (alas) a sober perspective, The Blue Bird is both frustrating and delicious in its conjuring of a futuristic world of blue-wigged mad scientists pursuing endangered animal and plant species, in addition to more obscure, lecherous and nefarious goals." — John Del Signore

FILM: Tonight Scion salutes emerging filmmakers at their Easy 10 Filmmaker Series screening party. "From dynamic documentaries on Big Daddy Kane and the Vietnam-era U.S. military funk band East of Underground, to Max Perlich’s 'More Is L.E.S.,' the Easy 10 Filmmaker Series showcases unique cultural undercurrents and artistic forms of expression."
