Swiss pianist-composer Nik Bärtsch brings his long-running quartet Ronin to Saugerties with a sound that treats repetition as pulse, structure and atmosphere all at once. Bärtsch works in a zone between adventurous jazz improvisation, minimalism, funk and ritual music, with grooves that build slowly and lock in hard. Expect a seated-listening-room kind of concentration, but not a quiet one.
