Beatlemania reached Argentina during the early 1960s and inspired many local cover bands who sang predominately in English.[49] A definitive shift occurred with Los Gatos' 1967 single "La balsa," which established the distinctive sound and emphasis of Spanish-language lyrics that have defined Argentine rock.[49] The 1960s also saw the rise of groups like Almendra, Vox Dei, Manal, and Pedro y Pablo, and singer-songwriters like Tanguito, Moris, and Javier Martinez.
