[2] For most of the band's history, Yello has been a duo consisting of Dieter Meier and Boris Blank; founding member Carlos Perón left in 1983.

[3] The band was formed by Boris Blank (keyboards, sampling, percussion, backing vocals) and Carlos Perón (tapes) in the late 1970s.

Dieter Meier (vocals, lyrics), a millionaire investor and gambler, was brought in when the two founders realized that they needed a singer.

The LP Solid Pleasure, featuring the original short version of "Bostich" (extended to a hit dance single in 1981), was released in November 1980.

A documentary on Yello, Electro Pop Made in Switzerland, directed by Anka Schmid, premiered at the Riff Raff cinema in Zürich in September 2005.

[8] Yello's sound is mainly characterized by unusual music samples, a heavy reliance on rhythm and Dieter Meier's dark voice.

Guest vocalists have included Rush Winters, Billy Mackenzie, Stina Nordenstam, Jade Davies, Shirley Bassey, Heidi Happy and FiFi Rong.

Their most recent live performance was on third of November 2017 in Berlin, where they played their older and newer songs with additional musicians and background vocalists.
