A band whose name means "The Agates", made up of secondary school pupils, formed by Zbigniew Witek in the third year of the Power Engineering Technical School in Kraków, playing in student clubs and other places: community rooms, clubs and houses of culture, of which there were plenty in the 1960s.
      The band was active in the years 1965 - 1968. It broke up after its members passed their school-leaving exams.
