Happening Wednesday

MUSIC

Freddie McGregor and Dawn Penn The smooth rock-steady rhythms of Jamaica visit the East side when Dub Club presents a double bill of reggae legends. McGregor, whose career as a singer, musician and producer spans six decades, will treat fans to hits from his sizable repertoire, which features “Big Ship” and “Bobby Babylon.” Penn, known for her Studio One single “You Don’t Love Me (No, No, No),” has been sampled by Ghostface Killah and Rihanna, Lily Allen and others. The Echoplex, 1154 Glendale Blvd., Echo Park. 9 p.m. $10. (213) 413-8200. https://www.attheecho.com

Diego Garcia In his solo work, the former frontman for the New York City-based garage-rockers Elefant takes a turn toward modern-day troubadourism informed by his native Argentina. Folk artist Jenny O. opens. The Echo. 1822 Sunset Blvd. $15. 8:30 p.m. (213) 413-8200. https://www.attheecho.com

FILM

Battleship Potemkin As anyone who has taken an introductory film class can attest, Sergei Eisenstein’s sweeping 1925 film about a sailors’ rebellion during the abortive Russian revolution of 1905 is a cinematic landmark. This new 35-millimeter print, 20 years in the making, restores dozens of missing shots, all the original title cards and Edmund Meisel’s 1926 score. The Cinefamily, 611 N. Fairfax Ave., L.A. 8 p.m. $10. (323) 655-2510. https://www.cinefamily.org

ART

Paul Thek All art is ephemeral, but Thek’s work is especially so — many of his early sculptures and installations were made of perishable material and known as “meat pieces.” The upcoming “Diver: A Retrospective” will feature many pieces never exhibited in the U.S., but at this performance, actor Thomas Jane will read from Thek’s writings. Hammer Museum, 10899 Wilshire Blvd., L.A. 7 p.m. Free. hammer.ucla.edu
