ADA Trio is Fred-Lonberg Holm (cello, bass), Peter Brötzmann (sax) and Paal Nilssen-Love (dr).
They have been touring recently, and on the video they are playing at London´s Café Oto, with drummer Steve Noble joining. The Liminal reviews that concert.
I sure hope they will be touring again!
ADA Trio released an album on PNL in 2011, and why not read a review over at Free Jazz, before you go looking for it.
