One of the many underrated artists coming out of the graffiti writing movement is the Giessen city based Hate one. His work appeared from the beginning of the German writing scene. He took his first steps around 1985, got down with such famous crews like FBI and TRD and developed his style further on from classic stuff
over semi-3D and also sculptures
to the fotorealistic paintings he is known for in the present. Though his work is focused mainly on canvas and MDF plates, he is still rocking fresh pieces on the walls from time to time. If you want some impression of his high quality artwork nowadays, you will find them here.
