His next album, "KOMEDA – The Innocent Sorcerer", attracted especially widespread interest. It was unique in several regards. Pierończyk performed pieces composed by someone else for the first time, and more importantly, the interpretation included no piano. The experiment, however risky, turned out to be a success. The album was hailed as the best interpretation of Krzysztof Komeda’s music since Tomasz Stańko’s "Litania" (Litany, trans. MG), and Pierończyk was acclaimed as a visionary, by, among others, critics from the American PopMatters magazine and the world-famous All About Jazz portal. It received five Fryderyk Awards nominations and was recognised as the best jazz album of the year, while Pierończyk won in the Jazz Musician of the Year category.
Pierończyk’s collaboration with Miroslav Vitous, a world-renowned double bassist who has recorded with, among others, Miles Davis, Wayne Shorter, and Joe Zawinul, turned out to be especially fruitful. Their first album, "Wings", was nominated for the 2016 Fryderyk Awards in the Jazz Album of the Year category, and Pierończyk also received a nomination for Artist of the Year. The second album by the duo, "Ad-lib Orbitis", was released by Austrian label PAO Records and contains 16 improvised pieces composed by the two musicians, recorded in a studio owned by Vitous.
Over the more than two decades of his musical activity, Adam Pierończyk – once perceived as the biggest hope of the Polish jazz scene – has become one of its greatest representatives. He performs all over the world, and has regularly won Jazz Forum’s annual poll in the Best Soprano Saxophonist of the Year category since 2003. His solo albums are as impressive as those releases on which he performs as a sideman. He has played and recorded with an array of brilliant jazz musicians, including Gary Thomas, Anthony Cox, Michel Donato, Andrzej Cudzich, the Oleś brothers, Vitold Rek, Wolfgang Pushnig, Herb Robertson, Mircea Tiberian, Maurice de Martin, Jacek Kochan, Ed Schuller, Anna Serafińska, Nelson Veras, Sam Rivers, Greg Osby, Jeff ‘Tain’ Watts, Trilok Gurtu, Ted Curson, Lage Lund, Orlando le Fleming, Joe Martin, Jean-Paul Bourelly, Avishai Cohen, Tomasz Stańko, Archie Shepp, Bobby McFerrin, and Joey Calderazzo. He has performed in clubs and at festivals in Europe (Poland, Germany, France, Italy, Belgium, Switzerland, Austria, the United Kingdom, Sweden, Denmark, the Czech Republic, Hungary, Bulgaria, Romania, Russia, Ukraine) and on other continents (in Kazakhstan, Kyrgyzstan, Morocco, Israel, the United States). In August 2019, Pierończyk performed at the Show of Hands Festival in Tehran.
Pierończyk also composes music for theatre performances, such as "Śmierdź W Górach" (Death in the Mountains, trans. MG) directed by Konrad Imiela and Cezary Studniak (2006), "Stalker" directed by Jakub Roszkowski (2012), "Szwejk: Na Tyłach" (Švejk. Behind the Lines, trans. MG) directed by Adam Walny (2013). In 2004-2005 he was the artistic director of Jazz aux Oudayas and Jazz Au Chellah festivals in Rabat, the capital city of Morocco. From 2011 to 2015 he worked as the artistic director of the Sopot Jazz Festival. From 2019 he took up the positions of artistic director and resident artist of the Jazz Juniors Festival in Kraków.
