International Pop Underground Convention

This article is about the music festival. For the compilation album of the same name, see International Pop Underground Convention (album).

Olympia's Capitol Theater (seen here in 2007) served as the Convention's main stage.

The International Pop Underground Convention (or IPU) was a 1991 punk and alternative rock music festival in Olympia, Washington. The six-day convention centered on a series of performances at the Capitol Theater. Throughout August 20–25, 1991, an exceptionally large number of independent bands played, mingled and collaborated at the Capitol and other venues within the Olympia music scene. A compilation of live music from the event was released later by the local record label K Records.
