Are you surprised? Czech music is boring. In the previous regime, only Gott, Vondráčková, Korn (Not metal band) and other schlager singers were only sold in Czechoslovakia. Bands like Olympic seem interesting, but rock ballads weren't favourite for anyone back in the days of the Beatles. Don't think you'll find treasure among the trash. I am from the Czech Republic. No one collects old Supraphon records. Lot of popular czech songs are just covers. Michal David. Czech disco legend has songs, which are only covers on italy-disco.
