20 April 1974
      The Sobeńko brothers from the band Jupitery had their school-leaving exams and an engineering thesis to defend. As a result, three members were left in the band.
      Some of the members of Big 5 left their band as well. The remaining members of both bands formed a new group, Hazard 74. It was based first at the Violinka club and later at the Kuźnia club. The remarkable thing is that the band (with small changes in the line-up) kept going for 30 years!.
