"These are short concerts, each lasting around 50 minutes, with ticket prices that put them within the range of a broader public," the festival's French artistic director Rene Martin told reporters.
Tickets cost 10 zloty (2.50 euros, $3.60).
The festival, in its second year, is a spin-off of France's "La Folle Journee", held in the city of Nantes in Brittany, western France.
A total of 27,000 people attended the 2010 edition, but organisers are hoping to double that this year.
