mercury's self-titled debut album was released in 1991 through independent record company eldorado. the lead single of the album, "swing da cor", which features olodum, became a number-one hit in brazil, and the album was soon known as "swing da cor". another song from the album, "menino do pelô", which also features olodum, became mercury's second top-ten hit in brazil, charting at number four. on the following year, mercury shut off from the record company and, ever since, produces her own albums to negotiate the distribution of them later with the labels that are interested.
