THE THEATER of Nations Festival, featuring theater troupes from a dozen nations, is taking center stage in Baltimore this month. This is the 20th biennial festival -- and the first to be held in North America -- so accessibility for American audiences was a prime consideration in choosing the participating troupes. (Translations and subtitles are provided where necessary). The festival schedule continues:

New York's Shaliko Company offers the first glimpse of "The Yellow House," a new musical based on the life and letters of Vincent Van Gogh and his brother, at Peabody School of Music, North Hall, June 20-23 and 25-29.

Czechoslovak actor/director Bolek Polivka and his Divadlo na Provazku troupe use masks and puppets in the largely wordless comedy-drama "The Jester and the Queen" at the Theater Project June 20-22.

The young Gardzience Theatre of Poland presents "The Life of Archpriest Avvakum" and "Marathon," predominantly visual plays based on Polish folklore, at St. Vincent de Paul Church June 21-28.

Montreal's Carbone 14 troupe brings "Le Rail," a theater piece about the power of the unconscious excerpted from D.M. Thomas' bestseller "The White Hotel" and Jack Henry Abbott's "In the Belly of the Beast," at the Baltimore School for the Performing Arts June 24-26.
