On Saturday, Soda Stereo’s Gracias Totales tour kicks off at the El Campín stadium in Bogota, Colombia. The 16 concerts in 10 countries -- which Soda drummer Charly Alberti describes as shows “for being together one last time” -- will be Latin America’s most repercussive rock band’s first live appearances without Gustavo Cerati, the group’s late magnetic singer, lyrical composer and guitarist, who died in 2014 at the age of 55.
