Masecki has a working relationship with the baroque orchestra Capella Cracoviensis. In 2013 they recorded the album Bach Rewrite, in wich Bach’s keyboard concertos are played on electroacoustic instuments from the 1970s while the orchestra, led by Jan Tomasz Adamus, plays on instruments from the 18th century. In a double concerto Masecki is joined by Piotr Orzechowski. The pianists improvise their cadenzas.
Since then Masecki is regularly invited to perform with the Capella. He has been invited twice to the Bach Festival in Świdnica, where the CC is orchestra in residence. He was also featured in their season concerts during the series Theatrum Musicum. Currently he is writing his Second Symphony to be premiered by the Capella in 2019.
