Mittelstandskinder Ohne Strom (also known as M.O.S.) are Christian Bruckhaus and Andi «N.D.M.» Muller, a psychedelic trance (form of electroinc music) project from Germany. Mittelstandskinder ohne strom, translated from German, means «middle class children without current». Because of the long name, M.O.S. is frequently used instead.
