É o Tchan! is a popular pagode band from Salvador, Bahia, Brazil that started in 1992.
Originally called Gera Samba, they exploded onto the scene with their hit single Segura o Tchan. Their first album, called É o Tchan (1995), sold triple platinum.
After legal problems, the name of the band changed from Gera Samba to É o Tchan, and with this name, they released the album Na Cabeça e na Cintura (In the Head and in the Waist), a reference to one of their signature dance moves.
