Polish music from the era of the Polish People's Republic (commonly referred to by the Polish abbreviation PRL) means different things for different people. For some, it is predominantly punk tunes from the Jarocin festival, for others it's the rock hits of the band Perfect, for others yet the classic hits of the 1960s and "70s. And although decades have elapsed since their creation, these tunes haven't lost a bit of their original freshness and energy. You can see this first-hand at the Poznański Chór Projektowy's concert where, backed by outstanding musicians, they will play The Best of PRL concert at Aula Artis.
