īandini wrote 'Ay mamá' as a tribute to her own mother, around ten years before releasing it, when she was 23 after becoming a mother herself she decided to put the song out. During composition of the song, the band experimented with different synthesizer sounds, and the line 'I don't know why people are so scared of our tits' was originally being recorded with a vocoder.
Wiwibloggs noted that 'Ay mamá' has choral verses build into an electropop chorus, which they had previously described as Bandini's particular style, and something that is 'anything but safe and lame' even within the context of the Eurovision Song Contest (ESC). Bandini has said that she does not only write songs about women, but that femininity is a large inspiration on her work. Bandini became one of the most popular singers in Spain over the COVID-19 pandemic, with her 2021 song 'Perra' becoming a ' feminist anthem' for its theme of vindicating femininity and for the wordplay of its title, ' perra'. Memé provides vocals, Navarro is the keyboardist, and Barenys, also originally a pianist, is their percussionist. Though considered a solo female act, Ribó performs as Rigoberta Bandini with her band formed of her partner, Esteban Navarro, and younger cousins, Juan Barenys and Memé (Belén Barenys). Paula Ribó González began performing as singer-songwriter Rigoberta Bandini in 2020 after having been in several girl groups in the 2010s.
