Koncert '68...Prague Spring remembered
Songs are great to discover a language. Recently there was a concert on Wenceslas Square remembering Prague Spring (Prazske jaro).
Listen to modern day singers like Vojta Dyk, Jana Kirschner, Marta Jandová, Xindl X, Lucie Bílá, Honza Křížek or Matěj Ruppert performing songs by Petr Novak, Karel Gott, Hana Hegerova, and Karel Kryl. Then find the original recordings of these songs.
And don't forget to listen to the moving Modlitba pro Martu (Prayer for Marta) by Marta Kubisova. There is also a separate vid on youtube with an English translation of this song
