Peter Br�tzmann collaborated with many artists in his career, regularly adding new compatriots into the fold, and Norwegian drummer Paal Nilssen-Love became one of his staunchest allies after the percussionist joined the Chicago Tentet in 2004. They worked in various contexts, including this inexhaustible, hard-hitting duo. Most of the albums they've issued have captured live performances, but in 2015 they made this stunning studio recording. As Nilssen-Love says in the liner notes, "Peter had acquired a contra-alto clarinet and was very enthusiastic about the sound of this instrument. I had also bought several Korean gongs which I hadn't used yet." They met up for a two-day session in Antwerp that August, and from the outset it feels different from much of their work.
