Santamaria, a Portuguese Eurodance project originating from Porto, was formed in 1997 by Filipa Lemos, her brother Tony Lemos, and Luis Marante. In 1998, before promoting their debut album, singers Diná Real and Magda Monteiro joined the group. The group's breakthrough came with their debut album Eu Sei, Tu És, released in 1998. In the following years, Santamaria released a series of successful albums including Sem Limite (1999), which became their best-selling album, featuring hits like "Tudo p’ra te amar" and a collaboration with Whigfield on "Happy Maravilha." They continued to release albums such as Voar (2000) and Reflexus (2001), winning the Globo de Ouro for Best Group in 2001. The group's success included numerous chart-topping hits, extensive tours, and multiple awards. On 13 October 2020, Tony Lemos died by suicide at age 48 following a battle with depression. Despite this loss, Santamaria continued their career, releasing Eterno in July 2021.
