Platinum Blonde, known briefly as The Blondes, is a Canadian rock band that formed in Toronto, Ontario in 1979. Vocalist Mark Holmes has been the only consistent member of the band since its inception.
In his 2016 book, Is This Live?: Inside the Wild Early Years of MuchMusic: The Nation's Music Station, Canadian songwriter and former MuchMusic VJ, Christopher Ward said of the band: "If ever there was a Canadian band that was tailor-made for the video era, it was Platinum Blonde."
The band was most prominent in the 1980s with singles such as "Standing in the Dark", "Not in Love", "Doesn't Really Matter", "Situation Critical" and "Crying Over You". In 1984 they were one of the top-selling Canadian bands in Canada, second only to Rush. At that time, the line-up consisted of Mark Holmes on lead vocals and bass, Sergio Galli on guitar, and Chris Steffler on drums. Scottish musician Kenny MacLean became the band's bassist and keyboardist in 1985.
The band broke up in 1989.
