Their album, released by Lado ABC, has become one of the most interesting music events in 2017 in the opinion of a large part of the Polish music industry. The trio, composed of Paweł Szamburski, Michał Górczyński and Tomasz Pokrzywiński, surprised many, reaching for medieval music, which was composed by the somewhat forgotten Piotr Wilhelmi from Grudziądz. It was the works of this 15th century artist that were the starting point for Bastarda and their work on the album Promitat eterno, based largely on the sound of clarinets and cello. The pianist Marcin Masecki also made a guest appearance on the album, and the whole album is a very original and fresh voice in this musical genre. At this concert they will present their third album Nigunim.
