Blennerhassett is a brief radio opera in one act by American composer Vittorio Giannini with a libretto by Phillip Roll and Norman Corwin.
A performance of the opera generally lasts less than thirty minutes, although the 1991 production added a 10-minute prelude set in a radio studio which reenacted the pre-broadcast preparation for the original premiere.
The plot centers on Stephen, a young follower of Aaron Burr, and his fiancée, Madeleine.
Stephen gathers a band of men on the island and plans to join Burr's forces.
When Madeleine unwittingly reveals the secret plan to General Wilkinson, he sets the militia on Stephen and his men.
