The name “Lucero” is a compound of the Romanian luciu (shining light) and ro (for Romania), and also carries the meaning “morning star” in Spanish.

Lucero Print is the publishing house set up by Horatiu Radulescu in the mid-1980s in order to have greater autonomy over how his music was made available to the world. Today Lucero Print is run by Catherine Marie Tunnell (managing director) with Dr Sam Dunscombe (editor / archivist).

The European Lucero Ensemble was an group active between 1996 and 2014 dedicated to realizing the works of Horatiu Radulescu. Radulescu served as artistic director of the festival, with assistance from Catherine Marie Tunnell (who also served as ensemble manager).

From the early 1990s until his death in 2008 Radulescu organised the Lucero Festival, a semi-annual multi day event dedicated to performing cutting edge works of spectral music composed both by him and other associates working in the field. Direction of the festival was carried out by a rotating roster of artists led by Radulescu himself, and coordination of the festival was undertaken by Catherine Marie Tunnell.
