With their farmer's daughter good looks, traditional instrumentation, flirty pop songs and flawless harmonies, it's easy to pan female country trio SHeDAISY as riding shotgun on the Dixie Chicks' bandwagon. But truth be told, Kelsi, Kristyn and Kassidy Osborn are blood sisters who've been singing and playing music together since they were little kids performing for friends and family outings. They never really played as a professional act until the late '90s, when they honed their three-part harmonies and relocated to Nashville. Lyric Street released The Whole Shebang in 1999, yielding three chart toppers that helped their debut go platinum. Their sophomore effort, Knock on the Sky, was released three years later with much less success, but 2004's Sweet Right Here unleashed the unstoppable single "Passenger Seat," which put them right back at the top of the country charts.
