Country rock: 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, Nashville West 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.

Confederate Railroad: Confederate Railroad is an American country rock–Southern rock band founded in 1987 in Marietta, Georgia, by Danny Shirley (lead vocals, rhythm guitar), Michael Lamb (lead guitar), Mark Dufresne (drums), Chris McDaniel (keyboards), Warren "Gates" Nichols (steel guitar) and Wayne Secrest (bass guitar).

In the 1990s, they released four more albums for Atlantic.

Bustin' Out: Bustin' Out is the second album by American country rock band Pure Prairie League, released by RCA Records in 1972 (see 1972 in music).  It features "Falling In and Out of Love," which ends in a segue to their hit song "Amie."  Amie then concludes with the main chorus of "Falling In and Out of Love."  Because of this interrelationship, many American classic rock and AOR radio stations play the pair of songs as a single track.  The album features a guest appearance by lead guitarist Mick Ronson on the track Angel No. 9.  The album ended up becoming far more popular a couple years after its release, during the height of the Country Rock, and Southern Rock boom of the mid-1970s.  By then, band leader Craig Fuller was no longer in the band due to draft board issues.  "Amie" was released as a single in 1973, and began receiving airplay mostly on college radio stations.
