Quarteto Athus is a Brazilian musical ensemble specializing in Christian and Gospel music. Renowned for their harmonious vocals, the group has dedicated themselves to spreading spiritual messages through song. Their repertoire includes a mixture of original compositions and well-known religious hymns, often sung in their native Portuguese language.

The ensemble's music transcends the conventional boundaries of Christian music by incorporating a variety of genres and styles. From the soul-stirring "Hino dos Desbravadores" to the contemplative strains of "Não Volto Atrás," their work is characterized by an emotive power and a devout spirit. Notably, Quarteto Athus provides playbacks, such as "Histórias do Celular (Playback)," which suggests a focus on musical arrangements that can be used for personal reflection or in a worship setting. Their release, "Singles I," indicates an ongoing process of musical creation and evolution, while live recordings like "Vai Começar... (Ao Vivo)" capture the vibrant energy of their performances, offering listeners a taste of their dynamic stage presence.
