The International Pop Overthrow is an American-originated music festival devoted to power pop music and related genres.
Taking its name from Material Issue's 1991 album of the same name, the festival began in 1998, and has been held annually in the LA area since then. "IPO," as it is also known, was created by former school teacher and power-pop journalist David Bash to congregate some of his favorite Beatles-inspired bands for live performances over a one week period in Los Angeles. All artists, both local and visiting, play a 30 minute showcase at a variety of clubs in the area. Music venues such as Spaceland, the El Rey Theatre, and The Troubadour would host these showcases, among others in the LA and Orange County areas.
Since its inception, the festival has expanded and held events in other cities such as Boston, Chicago, Liverpool, Nashville, Philadelphia, San Francisco, Phoenix,Seattle, and Vancouver.
From 1997 through to 2010, Not Lame Recordings released an annual CD compilation featuring the bands appearing at that year's festival.
