Travel / Good unpopular nightlife/cultural destinations in Poland [5]

Can anyone please let me know some off the beaten track destinations with good nightlife and cultural attractions in Poland.

Preferably university towns but not necessarily. I would rather not go to the Warsaws, Krakow's, Szczecin's, Wroclaw etc..

I would like to stay away from the big Polish tourist destinations if possible.

Any advice much appreciated.
