With an educational background in economics, law, and sociology from institutions in Barcelona and Madrid, Rossell's artistic journey took a significant turn in 1964 when he relocated to Paris, France.

There, he immersed himself in theatre and cinema training and became a key figure among the 'Catalan artists in Paris', collaborating frequently with contemporaries such as Jaume Xifra, Antoni Miralda, and Joan Rabascall.

Despite their varied professional backgrounds, Rossell collaborated with these artists on multiple projects, reflecting a shared interest in exploring the ceremonial and ritual aspects of art.
