Country rock is a subgenre of popular music, formed from the fusion of rock and country. It was developed by rock musicians who began to record country-flavored records in the late-1960s and early-1970s. These musicians recorded rock records using country themes, vocal styles, and additional instrumentation, most characteristically pedal steel guitars. Country rock began with artists like Bob Dylan, the Byrds, Nitty Gritty Dirt Band, the Flying Burrito Brothers, Gram Parsons and others, reaching its greatest popularity in the 1970s with artists such as Emmylou Harris, the Eagles, Linda Ronstadt, Michael Nesmith, Poco and Pure Prairie League. Country rock also influenced artists in other genres, including the Band, Grateful Dead, Creedence Clearwater Revival, the Rolling Stones, and George Harrison's solo work. It also played a part in the development of Southern rock.
Sometimes it takes an ‘American Woman’ to break into the US charts, and that’s what Canadian powerhouse rock group, The Guess Who did in 1970, being the first Canadian group to have a US chart topper since 1954. Powered by the soulful vocals of Burton Cummings and Randy Bachman’s driving guitar and sardonic songwriter, the Winnipeg-based band found international success throughout the 60s and 70s, until disbanding when Bachman left the group and went on to form the hugely successful, Bachman-Turner Overdrive, with their hit single ‘You Ain’t Seen Nothing Yet’.
During the mid-1980s, a group of new artists began to emerge who rejected the more polished country-pop sound that had been prominent on radio and the charts, in favor of more, traditional, "back-to-basics" production. Many of the artists during the latter half of the 1980s drew on traditional honky-tonk, bluegrass, folk and western swing. Artists who typified this sound included Travis Tritt, Reba McEntire, George Strait, Keith Whitley, Alan Jackson, Ricky Skaggs, Patty Loveless, Kathy Mattea, Randy Travis, Dwight Yoakam, and The Judds. https://www.youtube.com/watch?v=GVVwOl9eZdA
