Spotted on Twitter: announced today, Round Hill Music Royalty Fund Ltd. has acquired what appears to be a half-interest in Trevor's catalog, including much of his film scoring work. That is an interesting development, as I wasn't aware any of those rights would revert to Trevor at all.
This is the first major acquisition for Round Hill Music following their IPO offering, the company was founded in 2010. Trevor is following the recent trend of artists selling their publishing to music investment/song management companies such as Hipgnosis Songs Fund, which recently acquired a number of publishing and administration shares of various high-profile artists.
