ABSTRACT: Both previous radiomessages for aliens, Arecibo 1974 and Evpatoria 1999 (see http://ebe.allwebco.com/Science for details) were the logical ones and represented the binary stream of FM information, which should be arranged into two-dimensional forms to perceive by eye-like sense-organ. ... So, I suggest to implement the 1st Theremin Concert for Aliens from Arecibo or Evpatoria Radar facility. ... The theremin was invented 80 years ago, in 1920 by Leon Theremin. ...

There were four Messages from Earth to proposed aliens -- two material (Pioneer Plaque and Voyager Record) and two ethereal (Arecibo-1974 and Evpatoria-1999). ...
