Duo (Bologna) 2018 is a live duo album by American composer and multi-instrumentalist Anthony Braxton, released in 2018. The recording documents Braxton's exploratory approach to improvisation within avant-garde jazz, emphasising extended instrumental techniques, abstract melodic and textural development, and conversational interplay, and it situates the release within his later-career interest in intimate duo and small-group formats as vehicles for his compositional systems.
