Monday, December 22, at 11:59 PM, is the deadline for submissions to Collaboraction’s ninth annual Sketchbook Festival. The festival, which has always showcased short new plays, will also include “devised or ensemble-generated”–as opposed to scripted–pieces this time around. Collaboraction is inviting artists “of all sorts” to “create a new American fable lasting seven minutes or less.” Sketchbook opens next spring at the Building Stage, on a date to be determined. The devised portion will be curated by director Dexter Bullard. For more information and to submit, go to the Sketchbook site.
