Last night I caught a remarkable, mostly improvised performance by reedists Tobias Delius and Ab Baars here in Berlin within the cozy confines of KM28. The musicians are probably best known as long-time members of the ICP Orchestra, where they have built an astonishing rapport over decades of work together and the set revealed an almost telepathic degree of communication. Their performance ended with a gorgeous reading of ‘De Sprong, O Romantiek der Hazen’, a ballad by ICP co-founder Misha Mengelberg, that delivered velvety splendor, but the rest of the music was all made up on the spot.
