Pea Sized is Pia Kayser and Karsten Kayser from Wiesbaden, Germany, who started seriously making music together in 2008. Their music is atmospheric alternative/electronic, mostly downtempo with a somewhat dark touch. Before this, Karsten had been playing with a number of local bands for over a decade, mostly as bassist. Official site: http://peasized.net/. In addition to conventional instruments such as guitars, synthesizers, and percussion, they tend to use (or abuse, if you will) things like melodicas, children's toys, and various other things that produce some kind of sound.
