Bard and bomb Set in 1605, Bill Cain's metafictional historical thriller, Equivocation, concerns a certain ink-stained wretch named Shagspeare who receives a royal commission to write a play about a plot to blow up the king and his ministers. As the playwright and his cohort go over various permutations of the Gunpowder Plot (with elements and allusions to works we think of as being by a Mr. Shakespeare, not Shag), the writer is caught between politics and art. The show goes on at 2 p.m. Sunday at the Arden Theatre Company, 40 N. Second St., and continues on a Tuesday-through-Sunday schedule to Dec. 13. Tickets are $36 to $50. Call 215-922-1122.
New sounds Using a gridlike score to guide the improvisations, Adam Rudolph's Go Organic Guitar Orchestra melds free jazz and world beat. Conducted by the avant-garde pioneer and composer, the 10-member ensemble plays at 8 p.m. at FringeArts, 140 N. Columbus Blvd. Tickets are $15. Call 215-413-9006.
World music Argentinian Israeli bassist Fernando Knopf and his quartet the Latin Power mix salsa and Middle Eastern rhythms at 7 p.m. at International House, 3701 Chestnut St. Tickets are $15. Call 215-387-5125.
Smooth criminal In his day, comedian Raymond Griffith was considered the equal to such geniuses as Charlie Chaplin, Buster Keaton, and Harold Lloyd - but, sadly, little of his silent-film work was preserved. A childhood illness left him unable to speak above a whisper, ending his on-screen appearances with the advent of the talkies, and after a career as a producer, he drifted into obscurity. The invaluable Secret Cinema steps in with the 1925 classic Paths to Paradise, a wild heist flick in which Griffith plays his top-hatted, mustachioed, suave character as a con man forced to team up with a female competitor to steal a diamond necklace. The rediscovered film (still missing the final reel) screens, with live accompaniment by Don Kinnier, at 7:30 p.m. at the Woodmere Art Museum, 9201 Germantown Ave. Admission is free. Call 215-247-0476.
Key player The sensational pianist Cecile Licad plays an intriguing recital of works by Alexander Reinagle, Edward MacDowell, Elie Siegmeister, and Charles Tomlinson Griffes at 8 p.m. at the American Philosophical Society, 105 S. Fifth St. Tickets are $24. Call 215-569-8080.
Still truckin' Formed as a side project during a Jefferson Airplane touring break in 1969 (and named after a heckler's attempted joke during a song) the acoustic blues duo Hot Tuna - bassist Jack Casady and guitarist Jorma Kaukonen - is still going strong. They play as a Thanksgiving appetizer at 7:30 p.m. at the Keswick Theatre, Easton Road and Keswick Avenue, Glenside. Tickets are $35 to $45. Call 215-572-7650.
Double feature Get away from the football, family, and tryptophan haze and take in a movie (or two): The great Bryan Cranston plays the acerbic blacklisted screenwriter Dalton Trumbo, who took on the anticommunist hysteria of the 1950s (and won two Oscars while banned) in Jay Roach's biopic Trumbo; Saoirse Ronan plays a homesick Irish immigrant in 1950s New York in John Crowley's fine romance Brooklyn. The films screen at 5:30 and 8 p.m. at the Bryn Mawr Film Institute, 824 W. Lancaster Ave., Bryn Mawr. Tickets are $12; $9 seniors; $8 students for each film. Call 610-527-9898.
