2) Eaves was a german hardcore-band from Aachen/Germany. Their style is a mixture between fast melodic new school hardcore and some screamo- and mosh-elements. In some reviews it was called 'emo-violence'. Eaves's lyrics deal with personal and political subjects. They're mostly written in German, which allows them to express themselves in a deeper way.
