Open House Party (most of the time, shortened to OHP) is an American radio show hosted on Saturday nights by John Garabedian, and on Sunday nights, hosted by KVIL morning host Kannon. The show promotes itself as "the biggest party on the planet". It focuses on playing contemporary hit radio (CHR) music, also known as Top 40. The show differentiates itself from most Top 40 stations because it plays a fairly significant amount of electronic dance music. Unlike most radio stations or programs, OHP plays all music by listener requests. That means, that there are no automated playlists, and that every song played is by a request that a listener made. OHP started in 1987 and is syndicated to more than 40 stations in the United States.
