Heavysaurus is a heavy metal/hard rock band from Germany, that was formed in 2017. The band plays hard rock and heavy metal songs for children to get in touch with this style of music. Therefore the band mostly uses German lyrics and the track durations are not too long. The concept and the dino costumes were taken from the Finnish band Hevisaurus, which was the first incarnation of this project, formed in 2009.
