Recognized for her emotive and captivating voice, dreamy aesthetic, and folk influences combined with a pop sensibility, Cat Falcão has been a respected figure in the alternative music scene in Portugal since appearing in 2014 alongside her sister in Golden Slumbers. In 2018, she made her solo debut with the album "One," under the stage name Monday. In 2020, she returned with a different sound on the EP "Room for All," a collection of colorful, captivating, and vibrant songs.

In May 2024, she released the album "Underwater, Feels Like Eternity"—a dreamlike collection of tracks with delicate arrangements that encapsulate a period of deep reflection and seclusion in the artist's life. Monday herself produced the album. This year, she embarked on the project "Live Underwater," presenting intimate live versions of the tracks "Wasteland," "When I Love Another Man," "One Foot in Line," and "On and On."

This show is part of a cycle of monthly solo shows at MACAM promoted by Locomotiva Azul, focusing on the appreciation and dissemination of the work of its artists.
