Lubber Run Park's amphitheater is a busy place all summer long. The Arlington County Cultural Affairs Division's Arts al Fresco series books concerts featuring musical styles from classics to African drums to rock and folk and dance from a number of local companies. Movie nights take advantage of the collection built up by the Arlington Library. Arlington's professional theater with a national reputation, Signature Theatre has initiated a program to stage a concert version of a major musical as a free event each June.
The amphitheater at Lubber Run Park in the Arlington Forrest residential area has benches for about 750 in front of a stage that is elevated but open to the stars. It's flanked by twin towers of cinderblock and wood, and a cinderblock building behind it provides a back wall. Behind the benches are brick-terraced grassy areas for picnickers, bringing the total capacity for a performance to about 1,200.
