Thaleia is an ensemble dedicated to the performance and dissemination of baroque music written by women, founded in 2021 by Ángela Lobato del Castillo and Laura Martínez Boj. Following the criteria of historically informed performance, we want to fill the gap in traditional concert programmes that ignore the existence of women composers or add them in an anecdotal way. We defend the value of female creation through the presentation of our repertoire, our performers, our leadership, our visual identity and our research. As members of the Mount Parnassus Foundation, we support the coming together of women in music, creating networks of support with like-minded talents.
