Last saturday Anthony Pateras performed a concert at the Jazzclub Karlruhe. He played a prepared grand piano in a very uncommon manner.
He was accompanied by Natasha Anderson (Recorders/Electronics), Will Guthrie (Percussion/Electronics), Jerome Noetinger (Revox B-77/Electronics) and Clayton Thomas (Double Bass). They treated their instruments like mad. For example, the bass player put a number plate between the chords and hit it with a drum stick:
Though the concert admittedly was not my tase of music, it was very interesting to see them performing live. As the ignorant I am, I left after the first set anyway :) .
