OUR PICKS

Music

Hearing the Iguanas is like taking in the New Orleans Jazz and Blues Fest in a single sitting: you'll hear a little blues, a little R&B, a little rock and dashes of zydeco, Tex-Mex, salsa and anything else they take a shine to. Taste the Crescent City group's musical gumbo Friday at the Birchmere's Band Stand (703-549-7500) and Saturday at the Ram's Head Tavern in Annapolis (410-268-5111).

Exhibition

What could be more appropriate to the season than the vernal profusion of fronds, leaves, buds, fruit and flowers -- plus a couple of lowly mushrooms -- now on view at the National Museum of Natural History in "A Passion for Plants: Contemporary Art From the Shirley Sherwood Collection"? Call 202-357-2700. (See review on Page 49.).

Film

A nice movie triple for this weekend: Iranian director Abbas Kiarostami's "10" is an astute, documentary-styled look at one woman's life in her car, in modern-day Iran. It opens at the new American Film Institute theater in Silver Spring. See review on Page 37.

"A Mighty Wind," a wry mockumentary about a reunion of folk musicians, brings back the funny folks (Christopher Guest, Michael McKean and Harry Shearer) who gave you "Best in Show." See review on Page 34.

And in "Holes," an adaptation of Louis Sachar's novel, a teenager is sent to a juvenile facility where he has to dig holes every day. Until he uncovers something very special. See

review on Page 34.

Theater

Relationships under strain, a wife's disappearance and a neighbor's suspicions are strands that weave and unravel in Andrew Bovell's intriguing "Speaking in Tongues" at Round House Theatre through April 27. Jane Beard, Marty Lodge, Andrew Long and Elizabeth Long play multiple characters speaking dialogue as rhythmically complex as modern ballet. Call 240-644-1100.
