Yazoo

Yazoo (also known as Yaz in the United States) are a British synthpop duo from Basildon, Essex. They had a number of Top 10 hits in the UK charts in the early 1980s. Formed in late 1981 by former Depeche Mode songwriter Vince Clarke (synthesizer) and Alison Moyet (vocals), Yazoo were signed to Mute Records in the United Kingdom and (as "Yaz") to Sire Records in the United States.
