The story
APM Music came to be in 1983 as a joint venture between Zomba/Jive Production Music and EMI Production Music (which now are owned by Universal and Sony, respectively). Sam Trust, former head of ATV, founded APM as a joint venture between what is now held by Universal (which owns the Kosinus and Bruton library) and Sony (which owns KPM).
The company was primarily set up to distribute third-party music libraries. Its core business revolves around curation and guiding, where most music is specifically conditioned to fill a market need. Instrumental to such curation is a dedicated team of expert music directors with whom clients partner for creative collaboration.
