The 23rd Annual Bugs Bunny Film Festival with two-hour screenings from 11 to 5 p.m. Friday, Saturday and Sunday at The Brattle Theatre, 40 Brattle St., Harvard Square. General admission is $9.

The Brattle Theatre hosts its annual school vacation week marathon of classic Warner Bros. cartoons, with the “Looney Tunes Revue” – the classic shorts with Bugs Bunny, Daffy Duck and the rest of the weird, dysfunctional clan that taught us all how to do violence right: without consequences. Event information is here.

Art receptions and exhibitions on Friday in Central Square and Saturday in Cambridgeport. Free.

 “Orí-Ire: Rhymes, Rhythm & Reanimation” from 6 to 9 p.m. Friday at YWCA Cambridge, 7 Temple St., Central Square, features the works of Oríkì, who employs hairstyles and animal metaphors as mediums for exploring, portraying and projecting the essence of a person, much of it alluding to the naming traditions peculiar to the Yòrùbá of Southwest Nigeria. (Through February.) “Sanctuary” from 7 to 9 p.m. Saturday at Gallery 263, 263 Pearl St., Cambridgeport – the space’s first national juried exhibition of the year, with some 45 artists taking part – explores the place and feeling where harmony, beauty and stillness are shielded and allowed to flourish, whether it lifts us up and makes us feel big or shrinks us down to show us humility in the face of infinity. (Through March 17.)

W.E.B. Du Bois 150th Birthday Celebration concert from 8 to 10 p.m. Friday at University Lutheran Church, 66 Winthrop St., Harvard Square. Free, but donations are welcome. Reserve seats here.

The Du Bois Orchestra, under the baton of Nathaniel Meyer, celebrates Du Bois on the 150th anniversary of his birth, performing Samuel Coleridge-Taylor’s “Ballade for Orchestra, Op. 33 in A minor”; Richard Wagner’s “Prelude to Act I of Lohengrin”; and Antonin Dvorak’s Symphony No. 9. Du Bois, the first African-American to get a doctorate from Harvard, fell in love with Wagner’s romantic music and wrote about the piece prominently in his seminal “The Souls of Black Folk.” Dvorak’s exuberant and uplifting piece features Native American folk songs and African-American spirituals as the Czech composer explored the immigrant experience. And Coleridge-Taylor is one of the great underrepresented Black English composers. Information is here.

“Sound Atlas,” Longy’s New Music Marathon from noon to 11:30 p.m. Saturday at the Longy School of Music, 27 Garden St., Harvard Square. Free.

Multiple performances can be explored in different rooms in Longy’s historic Zabriskie House over nearly a dozen hours. The Neave Trio (above, in a photo by Arthur Moeller), Longy Chamber Chorus and members of the entire Longy community will present world premieres by composition students alongside pieces by Rzewski, Carter, Andres and Patterson. Information is here.

Fantastic Filming comedy festival from 7 to 10:30 p.m. Saturday at Green Street Studios, 185 Green St., Central Square. Free.

These local comics are performing their best material to be used in festival submissions, so expect to laugh a lot at the tightest five (or significantly) more that can be mustered by Valeria Dikovitskaya (above; click to see a video about her by CCTV’s Kristina Kehrer); Brandon Lee; David McLaughlin; Goo Phase; Todd Clay; and David Thomas. Information is here.
