Hamen is a symphonic power metal band from Joinville, Santa Catarina, Brazil, formed in 2014, fronted by vocalist Monica Hamen alongside guitarist Cadu Puccini. The band gained international exposure through inclusion on the Terrorizer magazine Fear Candy Latin America compilation and the Imperative Music Volume XVI DVD. Signed to MS Metal Records, their science fiction-themed approach places them among the more melodically ambitious acts in Brazil's southern metal scene.

Hydria was a symphonic metal duo from Rio de Janeiro formed in 2008, centred on vocalist Raquel Schüler and guitarist, composer, and producer Celo Oliveira. Their self-funded debut album Mirror of Tears (2008) earned the band opening slots for Within Temptation and Tarja Turunen on their 2008 Brazilian tours, significantly raising the band's profile. Hydria continued with Poison Paradise, the acoustic collection Acústico — The Acoustic Sessions (2011), and Freakshow (2013) before splitting up that same year.
