Yello is a Swiss electronica band consisting of Dieter Meier and Boris Blank. Yello's sound is mainly characterized by unusual music samples, a heavy reliance on rhythm and Dieter Meier's dark voice. Yello rarely uses samples from previously released music; nearly every instrument has been sampled and engineered by Boris Blank, who over the years has built up an original sample library of over 100,000 named and categorized sounds.
The music is composed by Boris Blank, who considers himself a perfectionist. When the tracks are mostly finished, Dieter Meier adds the vocal parts when fitting.
