The album is a recording of a concert which took place in 2013 in Warsaw during the "Ad Libitum" Festival. Both musicians are also composers, thus it comes as no surprise that their mutual playing has a clearly outlined structure. Their understanding of rhythm is superior. They recognize the character of space and fill it in a truly masterly fashion with the energy of their music. Despite their mature age they sound more lively and crisp than ever. Every concert they play is an opportunity for exploring new territories. The unknown, surprising and unpredictable quality of their music as well as the emotions it conveys infect the audience immediately. This music is always on the edge.
