Arrange your exhibit space into different areas to help people learn about this music.  Have one area focus on the early Celtic history of the music.  Have another focus on the style of traditional Appalachian music.   Explain how it was shaped by different cultures in America.  Then, take the project into the modern day.  Show performances of contemporary Bluegrass music and explain how this style grew out of Appalachian music.

Bonus:  You were contacted at the last minute by the people at the Smithsonian.  They said President Obama and his daughters are planning to visit the booth.  He asked if your group could make the booth more interactive for his daughters.  He wants you to show them how instruments are made and played.  Don't let them down!
