Walda Gang is a Czech rock band founded by Vláďa Šafránek, former singer of the group Harlej. The band focuses on rock adaptations of songs originally performed by Waldemar Matuška, as well as covers of other well-known Czech and international hits. Their repertoire includes popular tracks such as Eldorádo, Slavíci z Madridu, and Čert ví, along with pieces like Hudsonské šífy, Pověste ho vejš, and a Czech version of Bad Touch by the Bloodhound Gang. In 2016, due to health issues, Šafránek was replaced by singer Miro Šmajda, and Šafránek passed away in 2018.
