Joe's Pub, the cabaret space off the Public Theater, continues to prove itself as eclectic as any room in town. In addition to presenting artists from all musical genres -- including opera, jazz, reggae, rhythm & blues and experimental -- it presents a wide variety of theatrical talents. Case in point: among the spring attractions: Broadway star Sam Harris, Off-Off Broadway diva Queen Esther, and avant-garde playwright Ruth Margraff.

March 20 and 27, at 8:30 PM, Sam Harris will sing a selection of Broadway standards and popular songs from his new CD. On stage, Harris is best known for his role as a sleazy operator on pre-Disney 42nd Street in the musical The Life. He was to have played Al Jolson in The Jazz Singer, a show that never made it to New York.

* In other news, on April 25, at 8:30 PM, composer Fred Ho will conduct a performance of Night Vision, the "Vampyre Opera" he penned with Margraff. The highly percussive work recently had a staged run at HERE and was performed in concert at Cooper Union last fall.

Queen Esther, a self-styled diva who has performed at the Worth Street Theatre and the New York Fringe Festival, will bring her one-person show Queen Esther: Unemployed Superstar to the pub on April 27, at 8:30 PM. Jeff Cohen directs.

Past performers at Joe's Pub include Audra McDonald, Dawn Upshaw, Faith Prince, Adolph Green and Betty Comden, Anne Bogart, Ann Magnuson, Aimie Mann, Alice Ripley, Karen Mason, Randy Graff and John Pizzarelli. Ticket prices vary. Joe's Pub is located at 425 Lafayette Street (between East 4th Street and Astor Place). For information, call (212) 239-6200.
