For 10 years and more than 42 colorful issues, Twoj Blues (‘Your Blues’), through its stories, interviews, and CD and concert reviews, has encouraged Polish blues fans to listen to the blues and learn its history. That has encouraged the double-digit growth of blues festivals in the country. The magazine can be viewed on its website, www.twojblues.com, where blues fans around the world can see the first-class quality in every issue. The magazine is published by Delta (www.delta.art.pl), a publishing and booking agency, and utilizes journalists from Poland, the Czech Republic, Great Britain, Germany, Latvia, Canada, and the United States. Twoj Blues has subscribers in Poland, Slovakia, Germany, Belarus, the Netherlands, Canada, and the U.S., and an especially significant number in the Czech Republic, where — thanks to the similarity between the Polish and Czech languages — it is treated as the main source of information about the blues.
