In the early 1990s the numbers reached 100,000 visitors and in 21st century about 120,000–160,000 people are visiting the festival every summer.

At the moment Pori Jazz Festival is the biggest, best known and most popular summer event in Finland.

Now Pori Jazz offers a broad contingent of the world's leading artists ranging from long-established figures to up-and-coming stars.

The festival atmosphere in particular, created by the music, people, fine services and unique milieu, is second to none and highly appreciated among the visitors.

Numerous world-famous musicians (including, for example, Tori Amos, Kylie Minogue, Art Blakey, James Brown, Phil Collins, Chick Corea, Miles Davis, Alicia Keys, Paul Simon, Jamiroquai, Macy Gray, Mary J. Blige, Erykah Badu, Paul Anka, Kanye West, Sting and others) have performed at the festival through the years, as well as lesser-known groups from Finland and elsewhere.
