Due to Coronavirus ifa Gallery Berlin had to cancel a series of concerts where Mazen Kerbaj would invite close collaborators from Berlin, and ask them to bring along a guest to play a trio together. Now Kerbaj has found a way to replace these gigs by recording solo pieces while listening to the other musicians solos through headphones, both an homage and a an open letter to close collaborators who he cannot meet for the time being: This time he recorded a solo while listening to Tony Buck’s Tidal, an unreleased piece that the musician shared with him for this project.
