Stella is the fourth studio album by the Swiss electronic band Yello, first released in Germany, Switzerland and Austria on 29 January 1985, and in the UK and US in March 1985. It was the first album made by the band without founder member Carlos Perón, and with his departure the remaining duo of Boris Blank and Dieter Meier began to move away from experimental electronic sounds towards a more commercial synthpop and cinematic soundtrack style. As well as becoming the first album ever by a Swiss group to top the Swiss album chart, it was the band's breakthrough album internationally, helped by the success of the song "Oh Yeah", which gained the band worldwide attention the following year after it was prominently featured in the 1986 film Ferris Bueller's Day Off and then two years later in The Secret of My Success.
Recording took place from mid-1983 to mid-1984 at the band's Yello Studio on the shore of Lake Zurich. Blank had purchased two new synthesizers in 1983, a Yamaha DX7 and a Roland JX-3P, but the album was mostly written and created using the equipment he already owned, a Fairlight CMI Series II sampler along with an ARP Odyssey synthesizer, the Linn LM-1 and Oberheim DMX drum machines, a Roland VP-330 Vocoder Plus, a Lexicon Hall reverb unit and a Framus guitar.
