Classical Theatre Company, Mildred’s Umbrella Theatre Company and Stark Naked Theatre are teaming up to share a performance space at Spring Street Studios.

Like several other mid-sized and small theater groups, the three so far have functioned as nomadic companies, performing in various spaces around town.

Beginning with Stark Naked’s Dinner with Friends, playing Feb. 23-March 11, the companies will alternate productions in the space they are renaming Studio 101 at Spring Street Studios, formerly Divergence Music & Arts.

The next shows of the other two groups, however, will play at other venues as previously announced: Classical Theatre’s Uncle Vanya, playing Friday through Jan. 22 at Talento Bilingue; and Mildred’s Umbrella’s Dead Man’s Cell Phone, playing March 8-24 at Barnevelder Movement Arts Complex. Both companies will be staging their productions in the new venue by summer.

While the new arrangement will enable the companies to share a continuing home base, as well as certain administrative duties of the arrangement, each will maintain its separate identity and programming philosophy.
