Mariannah and Diego (MYD) is a Christian music duo with an electro-pop music style featuring rhythms known as "chill-wave," "tropical house," and EDM. MYD members include Mariannah Aguilera (voices, guitars, and keyboards) from Havana, Cuba, and Diego Archer (programming, composition, guitars, and keyboards) from Dallas, Texas. They met in 2016 on a mission trip and have been friends since. The duo was officially born on February 14, 2020, with immediate success. They write music from a distance, with Diego performing and arranging all instruments in Dallas; and Mariannah recording main vocals in Havana. Once recorded, the songs are mixed in Spain and mastered in England. They publish through American distributors and have been quite successful in Latin America. They also host a radio show called "Reaction Juvenil," featured on two stations: Panama City, Panama, and another in Quito, Ecuador. Their ministry consists of bringing God's word to Spanish-speaking youth and being a testimony of His love on earth.
