The Tony Award-winning Signature Theatre is looking for the next ‘Signature Idol,’ with the return of the very popular Signature Idol Competition being held during this year’s annual Open House on August 4th. The competition, now in its third year, will feature a panel of three celebrity judges providing their feedback on the best undiscovered singers in the DC region showing off their stuff in Signature’s MAX Theatre. Finalists will be chosen by Signature’s artistic staff, based on audition videos submitted by the July 16 deadline.
