Los Angeles Barea studied at the renowned Cristina Rota School of Theatre in Spain. She was discovered by director Pedro Almodóvar and made her acting debut in his Academy Award-winning film Women on the Verge of a Nervous Breakdown, which won the Oscar for Best Foreign Film. Following this success, Angeles worked with acclaimed directors such as Jess Franco and Álex de la Iglesia.

Los Angeles became a well-known personality, making numerous television appearances. She went on to host programs on MTV, National Television, Canal Plus, and Tele-Madrid.

Record company EMI-Chrysalis signed her to a recording contract, and she released four critically acclaimed albums with her band. Angeles was responsible for lead vocals, music composition, and lyrics. Her views on pop culture were featured in articles for national magazines and newspapers.

In Los Angeles, California, she directed and wrote a short film titled Buy Me a New Life. Encouraged by its success, Angeles wrote and directed her first feature film, The Paper Boat, produced by her own production company, SinAmor Films.

Los Angeles was inspired after working for six years with an environmental non-profit called Grades of Green, where she witnessed young people developing remarkable projects aimed at helping the planet. She was deeply moved by their innovative approaches to tackling issues such as plastic pollution, clean energy, water contamination, fossil fuels, and climate change. Motivated by their work, Angeles realized she wanted to showcase these young, brilliant minds and their groundbreaking solutions to global challenges. These young people, who she considers role models and heroes, are featured in Green SuperHeroes 2030, a project also produced by her company.
