David Bash is the founder and CEO of the International Pop Overthrow Music Festival, which is held annually in 16 cities around the world, including Los Angeles, San Diego, Portland, Seattle, San Francisco, Phoenix, Chicago, Detroit, Nashville, Atlanta, Austin, Boston, New York, Toronto, Vancouver BC, Stockholm Sweden, and Liverpool UK (at The Cavern Club).
 The festival is dedicated to bring classic pop music to the public.
 Although the festival has over the years featured several major label acts, such as Phantom Planet, Maroon 5 (under their previous incarnation, Kara's Flowers), and The Click Five, Bash tries to maintain the grassroots feel of the festival by featuring primarily unsigned bands, and presenting them in a festival platform with similar minded artists, where they will be appreciated by both the festival audiences and by each other.
 Bash personally selects all the artists.
 Each year, Bash produces a CD compilation on the Pop Geek Heaven label featuring bands that have played in any of the cities in which the festival has appeared.
